Adds a new Obsidian Theme using the new UDL2.1 syntax.

* Spaces between words now only appear in the single asterisk (*) syntax.
* Links can be single words.
* Most of the combinations of delimiters (bold text in italic text, etc) are now displayed properly.
* Escapes slashes (\) can now be used. Unfortunately, they only work like string escapes : \* this would be italic text with an \* asterisk in it *.

* Adds a new syntax_highlighter_test.html to test for combinations of keywords and delimiters, for example italic text inside bold text. This file uses strapdown so one can view how the  Markdown actually is converted by a parser simply by displaying it in a browser.
* Adds a new syntax_cheatsheet.md
* Changes the listed bugs in tests.md to better reflect what the shortcomings of the new UDL2.1 syntax are.
* This theme uses the "Firefox" color theme from the Kuler website : https://kuler.adobe.com/Firefox-color-theme-629495/

Refactors UDL, using the new UDL2.1 syntax for the Default theme.

* Spaces between words now only appear in the single asterisk (*) syntax.
* Links can be single words.

* Adds a new screenshot.png showing the display with new colors and new syntax.
* Changes the colors :  I thought that the colors for this theme didn't really "work" together, they were very different. So I created a Kuler, I used an "Analogous" rule and so at least the luminosity is similar. See https://kuler.adobe.com/Markdown-Notepad-Highlighter---Default-Theme-color-theme-2586886/
