* Added missing trigonometrics filter operators
This PR adds support to trigonometry operators, allowing to create spider graphs and other geometric shapes with filters.
* Adds the missing trigonometric filter operators
This PR adds support to the missing trigonometric filter operators (cos, sin, tan, acos, asin, atan, atan2), allowing to create spider graphs, [pie charts, donut charts, polar charts](https://ffoodd.github.io/chaarts/pie-charts.html) and other geometric shapes with filters, which was previously not possible without add-ons.
Example :
`[[2]cos[]] = -0.4161468365471424`

* Add documentation for the Trigonometric Operators
Accompanies code changes #6127
* Fix formatting of atan2 Operator.tid
Removed two empty lines at the end of the tiddler
* Add examples for the trigonometric operators
Accompanies code changes Jermolene#6127
* Fix version in the doc for trigonometric operators
This PR fix the content of the documentation tiddlers regarding trigonometric operators (#6131).
<<.from-version "5.1.20">> was changed to <<.from-version "5.1.21">>
* Fix formatting of atan2 Operator.tid
Removed two empty lines at the end of the tiddler
* Add missing parameter to atan2 operator
The atan2 operator needs two parameters (Binary Mathematics Operators), this PR adds the second one that was missing.
See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/atan2 for more technical info on the atan2 function.

* Add support for JSON-formatted tiddler store, and make it the default
The change to `getTiddlersAsJson()` is to allow experimentation
* Move JSON tiddlers into their own store area, and fix support for encrypted tiddlers
Also add a dummy old-style store area for backwards compatibility
The current arrangement is that JSON tiddlers will always override old-style tiddlers.
* Use the deserialiser mechanism to decode the content
* Refactor $:/core/modules/deserializers.js before we start extending it
Cleaning up the helper function names and ordering
* Drop support for the "systemArea" div
It was only used in really old v5.0.x
* Update deserializer to support JSON store format and add some tests
* Life UI restrictions on characters in fieldnames
* Add another test case
* Correct mis-merge
* Remove toLowerCase() methods applied to fieldnames
* Insert line breaks in output of getTiddlersAsJson (#5786)
Rather than have the entire store on one line, insert a line break
after each tiddler.
* Refactor #5786 for backwards compatibility
* Only read .tiddlywiki-tiddler-store blocks from script tags
Prompted by @simonbaird's comment here: https://github.com/Jermolene/TiddlyWiki5/pull/5708#discussion_r648833367
* Clean up escaping of unsafe script characters
It seems that escaping `<` is sufficient
* Add docs from @saqimtiaz
Thanks @saqimtiaz
* Docs tweaks
* Remove excess whitespace
Thanks @simonbaird
* Fix templates for lazy loading
* Remove obsolete item from release note
* Clean up whitespace
* Docs for the jsontiddler widget
* Fix whitespace
Fixes#5840
* Comments
* Fix newlines in JSON store area
* Remove obsolete docs change

* Make currentTiddler variable consistent in subfilters and filter run prefixes
* Updated filterun prefix and subfilter operators to use ..currentTiddler instead of outerCurrentTiddler
* Replace css-escape-polyfill.js with escapecss.js utility module
* Add $tw.utils.escapeCSS() method and invoke that function within the
escapecss operator.
* Add test cases for the "escapecss" filter operator
* Fix $tw.boot.doesTaskMatchPlatform() so it works as expected if
a module's export.platforms contains more than one values
* Add missed files to the last commit
Fixes#5246. Now the reduce operator and :reduce filter run prefix will
both return empty output when their input is empty, so that both can be
chained together with the else operator or :else prefix.
Default with no suffix is pre-5.1.23 behavior, escaping all Unicode
characters for maximum compatibility (avoids encoding issues). New
"rawunicode" suffix allows passing through Unicode characters U+0080
and up unchanged, for cases where you know your tools are handling
encoding correctly and you want less verbose escaping.
* Extend toggle operator to support optional second operand to toggle a value pair
* Added tests for extended toggle filter
* Updated docs for toggle operator
* Add suffix and parameter to trim operator
Fixes#4809
* Unit tests for new trim operator parameters
* Mention trim operator in 5.1.23 release notes
* Address review comments
* Move regex escaping into utils.js trim functions
This way the trimPrefix and trimSuffix functions from utils.js are safe
to call without regex-escaping their parameters, which should make them
easier to use from other parts of the Javascript code.
* The `!has[tags]` filter didn't work because "tags" is an array
The negated `has` filter only considered empty strings, but not empty
arrays (such as the `tags` field).
* Add tests for `has` filter operator with array-like fields (tags, list)
* add a new-line before the log text to increase readability of the test output
* make eslint, jslint happy
* extend fields-widget with include/exclude/sort/reverse and fields-filter with include and exclude params plus DOCS
* remove new-line
* remove eslint settings
* restore old eslint settings
* remove typo
* add escapecss filter
this filter would allow creating valid css classes from titles containing special characters
we assign a class to an element using `encodeuricomponent[]` so that the class name is encoded
in a stylesheet we create the classname by `<title>escapecss[]` which applies the uri encoding and escapes characters that need to be escaped
* Update encodings.js
* refactor tagToCssSelector, add escapeCssSelector
* use escapeCssSelector
* escape using CSS.escape if it's available
* Update encodings.js
* revert factoring out escapeCssSelector
* First pass at modular wiki indexes
An exploratory experiment
* Fix tests
* Faster checking for existence of index methods
We don't really need to check the type
* Use the index for the has operator
* Fix typo
* Move iterator index methods into indexer modules
Now boot.js doesn't know the core indexers
* Fix up the other iterator index functions
* Fix crash with missing index branch
* Limit the field indexer to values less than 128 characters
* Fallback to the old manual scan if the index method returns null
* Sadly, we can no longe re-use the field indexer to accelerate the `has` operator, because the index now omits tiddlers that have field values longer than the limit
Still need to make the index configuration exposed somehow
* Rearrange tests so that we can test with and without indexers
We also need to expose the list of enabled indexers as a config option
* Test the field indexer with different length fields
So that we test the indexed and non-indexed codepaths
There are other ways we could add maths to TW5 (including @EvanBalster's awesome https://github.com/EvanBalster/TiddlyWikiFormula) but the approach here has the merit of simplicity because it reuses the existing filter evaluation mechanism. That means that it's not ordinary "2+2" maths, it's a unique list processing language...
Docs to come
Fixes#254
* Refactored the is operator for simplicity and efficiency.
* Improve `is` filter documentation.
* Update is.js
* extracted `subops.length` to `num_of_subops`
* renamed `subop` to `operator` for clarity/differentiation from `subops`
* refactored to avoid using a `Set` object.
* Update is.js
* Modify the is operator to allow multiple types to be specified.
* Fixed indentation.
* Fixed indentation.
* Rewritten to maintain input order when multiple filters provided.
* Updated documentation.
