* 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
