Enhance the "Compress CSS" mode Rated 4 out of 5 stars

FireFile is a great plugin which will certainly make me save lots of time in the near future.

However I have a few suggestions in order to enhance the "Compress CSS" options :

- strip the quotation marks in the background-image declarations. They're useless, yet FireFile adds some even when there were none before the CSS get compressed ;
- create an option to preserve line-breaks after the closing curly braces ;
- create an option to preserve CSS comments : in a team of a dozen front-end developers, using comments in CSS are really helpful.

Many thanks for your work, Tobias !
