* 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
* Add optional KaTeX support to the tiddlywiki/markdown plugin.
Uses the remarkable-katex plugin 1.1.8 by Brad Howes to enable KaTeX support if
the tiddlywiki/katex plugin is installed. Fixes#2984.
