Ask for comment character when toggling line comments when unknown

[thedaniel]

If I'm editing a file (in this case play/play's mpd.conf) and there isn't a known comment syntax for the file, when I toggle line comments, Atom should ask me what the comment character is. You know, like comment-region in Emacs.

Integrating this would be a solution to #13370
