Title: CSS and HTML Line Comment 

Adding line comment to CSS and HTML as suggested here: adobe/brackets#2119

The implementation is like Sublime's where the entire line (avoiding empty spaces at the start) gets commented if there is no selection, and just does a block-comment if there is a selection.
