MarkDown Extension Set 0

I don't have a V1 yet, but this is pretty handy. It's being implemented for many langauges, so if you wanna use it elsewhere you can probably check in a version for a language.
This basically adds a few neat things I use a lot when making webpages.

Its also easy to use!
PHP:

require("mdes0.php");
$mdes = new MDES();
echo($mdes->text("{#FF0000:Hello Markdown!}"))

Javascript Client:

//Earlier use <script src=mdes0.js></script>
var parsed = mdes.parse("{#FF0000:Hello Markdown!}")
console.log(parsed)

Javascript Server:

var mdes = require("./mdes0.js")
var parsed = mdes.parse("{#FF0000:Hello Markdown!}")
console.log(parsed)

Link Lists:

-a /path/to/file:What the user reads
Just don't use a colon in your link. Use // if you need HTTPS or HTTP. If you want mailtos and websockets first of all websockets are a bad idea and second of all then I would have to rewrite the regex.
=a /path/to/file:What the user reads
The same as before, but it has an leading to external.svg. It's an icon that I have a copy of.

Colors!

{#hexcodethatcanhavealpha:text}
{:#bgcolor:text}
{#color|#bgcolor:text}
{:#bgcolor|color:text}
That's a lot of combinations. Right now there's only support for hex codes, sorry for RGB and RGBA users out there, we don't do that.

Easy Subtext and Supertext:

[^:supertext]
[v:subtext]
It's that simple now.

Underlines

_underlined_
This does mean that underscores mean underline, you'll have to use stars.

That's it for the changes. If you want to add support for a language, simply create a new file called language-name.txt in the languages folder. In that file, put whatever code necessary, including any needed packages outside the languages folder. Any uses of ?0, ?1, and ?2 will be replaced with: A JSON object of the regex as a key and the replacement as a value, a JSON array of the regexes (Keys of ?0), or a JSON array of the replacements. (Values of ?0).
