added tmux syntax highlighting to ST2
Changed Git editor to Vim, added filetype on to vimrc.

Calling out to ST2 from within tmux for git commit messages fails. Switching
to vim instead.

Added `filetype on` statement just prior to `filetype off` required by Pathogen. Best
to turn it on prior to turning it off.
Added `filetype on` statement prior to pathogen required `filetype off`.

Turning filetype off is required to call pathogen, however, turning filetype
off when it is already off causes a non-zero exit code, which causes Git to
reject the commit message. Adding a `filetype on` statement just prior to
turning it off eliminates the issue.
