Add support for JSON-formatted tiddler store, and make it the default (#5708)

* 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

-TW has two approaches to save the user data. These approaches depends on way you use TW. either you use node.js as a server for TW its saves the tiddlers as plain text in different files or you use TW as standalone in a browser it persists the data within the HTML-File in two Div-Areas depending on whether the encryption of the TiddlyWiki is activated or not. If the TiddlyWiki is not encrypted the data is stored in the Div-Area called "~StoreArea". Every created Tiddler is stored in a own Div-area with a few custom values. An example of a saved Tiddler is shown below (\prettyref{lst:data-div}).

-The Div-Area has the same attributes like the standard tillder fields, listed in  [[TiddlerFields|https://tiddlywiki.com/#TiddlerFields]], all attributes which are not in this list are parsed as a custom field. The only required attribute is the name attribute, all other attributes are optional.\\
-With a activated encryption the data is stored in a special Div-Area called "encryptedStoreArea". TiddlyWiki uses the Standford [[JavaScript Crypto Libary|http://bitwiseshiftleft.github.io/sjcl/]]. The encrypted Tiddlers are saved in a JSON string within this Div-Area.

+
+!!! Without encryption
+If the ~TiddlyWiki is not encrypted the data is stored in a `<div>` tag with an `id` attribute of "storeArea".
+
+```html
+<div id="storeArea" style="display:none;">
+```
+
+Within the store area `<div>`, each tiddler is stored in its own div. 
+
+//Tiddler DIV//
+
+Each tiddler `<div>` has an attribute corresponding to each of the tiddler's fields, except the text field which is saved within a `pre` tag within the `<div>`. Note that all attributes and therefore field names must be lowercase letters, digits or the characters `-` (dash), `_` (underscore) and `.` (period). The only attribute that is required is `title`, all other attributes are optional. All attribute values and the text field within the `pre` tag are HTML encoded.
+
+Example:
+
+```html
+<div id="storeArea" style="display:none;">
+<div created="20140611153703343" modified="20140611153734589" tags="testTag" testfield="testvalue" title="TestTiddler" type="text/plain">
+<pre>testText</pre>
+</div>
+</div>
+```
+
+
+
+!!! With encryption
+
+If the ~TiddlyWiki is configured to encrypt its content, the tiddlers are stored as as an encrypted JSON string in a `<pre>` tag with the `id` attribute "encryptedStoreArea". 
+
+```html
+<pre id="encryptedStoreArea" type="text/plain" style="display:none;">
+```
+
+~TiddlyWiki uses the [[Stanford JavaScript Crypto Library|http://bitwiseshiftleft.github.io/sjcl/]]. 
+
+---
+
+!! From ~TiddlyWiki v5.2.0
+
+From v5.2.0 onwards, ~TiddlyWiki introduces a new JSON based format for the tiddler store area for unencrypted content, while retaining support for the older store area formats described above for backwards compatibility. The store area format remains unchanged for encrypted content.
+
+
+!!! Without encryption
+
+By default, all tiddlers are now stored as an array of JSON objects inside a `<script>` tag with the `class` attribute "tiddlywiki-tiddler-store" and the `type` "application/json". For better readability, every tiddler object begins on a new line. There are no longer any restrictions on characters that are allowed in tiddler field names. However, `<script>` tag store areas must encode the `<` character to `\u003c`.
+

+
+To retain compatibility with external tools that might insert tiddlers by directly manipulating the ~TiddlyWiki HTML file, the older format `<div>` store area is still present in the HTML file immediately after the new `<script>` tag store area:

+]</script><div id="storeArea" style="display:none;"></div>
+```
+
+Any tiddlers in the older format `<div>` store area are also loaded before tiddlers from the new `<script>` store area. 
+
+!!! Multiple store areas and precedence
+
+Tiddlers from the new `<script>` tag store areas are loaded in the order of their store areas in the HTML file. Therefore if the same tiddler exists in two different `<script>` tag store areas, the tiddler from the later store area takes precedence. Note however that tiddlers from `<script>` tag store areas always take precedence over tiddlers from the older format  `<div>` store area. Therefore a tiddler from the older `<div>` store area can never overwrite a tiddler from  a `<script>` tag store area.
+
+Note that all `<script>` tags with the `class` attribute "tiddlywiki-tiddler-store" have their content parsed as JSON and loaded as tiddlers. This allows external tools to easily insert tiddlers into an HTML file by appending additional `<script>` tag(s) at the very end of the HTML file:
+
+```html
+</html>
+<script class="tiddlywiki-tiddler-store" type="application/json">[
+{"created":"20210525212411223","text":"This is some test text","tags":"[[test tag]] [[another tag]]","title":"My new tiddler to insert","modified":"20210525212430577"}

+title: Data Storage
+
+~TiddlyWiki has two approaches to saving the user data (tiddlers) depending on whether you are using the single file version, or are using the node.js server.
+
+~TiddlyWiki on node.js saves each tiddler in a separate text file. For details on the file formats supported for tiddlers on node.js, see [[Tiddler Files|https://tiddlywiki.com/#TiddlerFiles]].
+
+The single file version of ~TiddlyWiki saves the tiddlers within the HTML file. See [[Data Storage in Single File TiddlyWiki]]
