Rewrite most of this stuff.

After some thinking, I think it would be a better thing to create three separate libraries:

• A CSS parser
• An HTML parser
• A minifyer.

Lua-minfy would then only handle the minifying of the trees generated by the parsers.

This would create a better separation of functionalities, and more importantly no longer rely on a really naive html parser that I wrote only for minifying.
