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 Co-authored-by: Simon Baird <simon.baird@gmail.com>

The jsontiddler widget is used in system templates to generate JSON representations of tiddlers for saving.
