Committing changes to Gemfile for lunchy.
Add global rbenv gemset.
Removed .bash_login

This is something that should be put on each individual machine. It may make sense
to have a basic one in etc if I use a similar one all the time.
Update custom.el Emacs packages and ruby-mode files.
Add linux-gnu to the $OSTYPE.

This also adds color to Linux prompts as a result.
Move the PS1 prompt into bash_profile and out of bashrc.
