Add uncommented alphabetical order

[bthorben]

We are developing according to the Google Styleguide, which dictates sorting the values alphabetically. As this is a popular technique, I think it would be good to have a maintained, high quality list shipped with CSSComb.

First of all, this repo is deprecated because it's based on old PHP-version of CSScomb.
Here is a new one: https://github.com/csscomb/sublime-csscomb

Also, CSScomb 3.0 allows to sort properties alphabetically with just two lines in config:

...
"sort-order": ["..."],
"sort-order-fallback": "abc",
...

See docs for more info: https://github.com/csscomb/csscomb.js/blob/master/doc/options.md#sort-order-fallback
Sublime plugin will be updated later this week.
You can subscribe to the issue here: csscomb/sublime-csscomb#20
