* Rename markdown to markdown-legacy
* Change how default renderWikiTextPragma value is displayed
To prevent out-of-sync, dynamically display the default value of
renderWikiTextPragma from the shadow tiddler instead of hard coding
the text in the "usage.tid".
* Repackage remarkable-based markdown plugin as markdown-legacy
- Rename plugin title to $:/plugins/tiddlywiki/markdown-legacy
- Add support for "text/markdown" MIME type and set that as the default
when creating new markdown tiddlers
* Create new markdown plugin
* add support to text/markdown MIME type
* remove linkify and linkNewWindow config options
- linkify feature should be controlled by "extlink" TW parser rule;
enabling markdown's linkify option will interfere with parsing
- remove the possibility to open external links in the same tab/window
to match TW's behavior
* Ignore latex-parser wikirule in rednerWikiTextPragma
* Prevent camel-case link text from generating a link
* Update editions/markdowndemo
* Produce better parse tree
* Improve markdown/tiddlywiki integration
- widget block should not interrupt paragraph
- ignore tw-syntax links inside markdown-syntax links
- remove repeated renderWikiTextPragma parsing
- more efficient findNextMatch when examining tw rules
* Update user docs
* Replace includes() with indexOf() for legacy browsers
TiddlyWiki passes the MIME type of the tiddler to highlight.js as the
"language brush", but it turns out that highlight.js doesn't actually
understand MIME types. This commit introduces a configuration mapping
between common MIME types and highlight.js language brushes
Fixes#2535
