* 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.

* Following code styles.
Moving getInt to utils.
* Removing unwanted spaces introduced by me
Spending a bit more time with Chrome dev tools, and further to 254e1ca, this optimisation reduces the rendering time for the sample TOC from 1.9s to about 0.9s...
I used this test:
console.time();for(var t=0; t<200; t++)
{$tw.wiki.filterTiddlers("[all[tiddlers+shadows]sameday[20170210]]");};c
onsole.timeEnd()
Before this patch, I got speeds of approx 190ms, versus 140ms
afterwards.
Note that the ability to add a cache property like this is only
possible because tiddler objects are immutable.
given a list `A B C D` if I run `A B C D +[move:-1 [A]]` I get `B C A D`. However, if I were to do `A B C D +[move:1[D]]` it doesn't wrap around, and I get `A B C D`. This fixes that such that `A B C D +[move:-1 [A]]` gives 'A B C D`
* return all wikiparserrules w/o operand
* simpler layout & code / updated instruction details
Also wanted to link each rule to the official docs using a dictionary at
`$:/language/Docs/ParserRules/`. However, without #2194 this is not
doable.
* Change the negation logic to address an edge case
Make it possible to get an interval ending with yesterday or starting with tomorrow.
* "days" filter: adjust documentation
List fields (such as tags) when evaluated to produce tiddlers result in empty arrays. Using the exact not equals, an empty array is not the same as an empty string. By using equivelent not equals, we state that the field is either != "" or anything that can be coerced to "". Which, based on https://dorey.github.io/JavaScript-Equality-Table/ is `false` `0` `[]` or `[[]]`` neither `false` nor `0` can be set as a tiddler field as both will end up being quoted (`"false"`, `"0"`) so this should work.
