Add vimrc to version control

- Borrowed with a few edits from https://github.com/begriffs/vimrc
WIP: Silence rvm error

- Start by adding contents from ~/.profile to bashrc, ensure rvm path is first in $PATH
- Still getting a "Error loading RubyGems plugin" message on terminal start
- Was getting a "Warning! PATH is not properly set up" message in rvm
Silence 'Error loading RubyGems plugin' error

- Not sure why it was coming from that export statement; I'll have to figure it out
