[TxMt] Bundle to alphabetize CSS rules

[Thomas Aylott - subtleGradient]

Personally this comment would confuse me for my own CSS. But I can  
imagine it being useful for working with other peoples crazy CSS files.

There are already reformatting macros in the CSS bundle that I made to  
completely compress or pretty-print all your rules. It might make  
sense to merge these commands somehow. Depending on the speed of the  
php.

Check out the regex I use in those macros. I tried to make it pretty  
flexable and just ignore the contents of of the rules. I haven yet  
heard of anyone running into a rule that my redormatter breaks.
