Title: Allow to preserve important comments in minified CSS output while not using keepComments settings 

Hi james,

In the recent project i was working on, i needed to keep some meta tag comment even after the CSS minification.

/*!
* Example of sticky comments
*/

This is pretty much in inline witht the what clean-css folks did (https://github.com/GoalSmashers/clean-css)

I hope someone could find it useful and we can integrate this
