Doesn't work with rules like background images, gradients...

[Shakarhaba]

Line 50 should be changed from:
/[\w\s.-:='*|?^+/;#%]+}{1}/

to:
/[\w\s.-:='*|?^+/\,();#%]+}{1}/

Note that GitHub is removing some backslashes. View http://pastebin.com/1y56eb8E for correct Regex code.

So rules like the next one are parsed:
background: -webkit-linear-gradient(top, #ffffff, #fcf8e3);
background: url('../images/foo.png');
