Adding a few more files for syntax highlighting in Ruby mode.

Vagrantfile, Capfile, etc. Also match on [.]yaml and [.]god.
Highlight lines over 80 characters.

I do a fair amount of editing in the terminal. 80 characters is good enough to stop
and add a damn newline. This will warn me if I am writing obtusely long lines.
Updating changes to fix various modes.

More ruby and less things that I don't use. Fix the themes.
Fixing changes for merging.
