Clean up exposure of the grep command

Browse Source 
This change breaks up the determining of the user's grep command, and
the arguments it sends it.

Configuration is now:

    let g:gitgutter_grep_command = 'grep --color=never -e'

This makes it easier for users to configure now, though not quite as
flexible.
