Title: Add 'line' highlighter for the whole buffer

This is a simple highlighter that applies to the whole buffer. I use it to emphasize the command line by making it bold.

I am not too familiar with Zsh command line highlighting, so if this is already trivial please enlighten me and close the pull request. :-)
