Hawk's fork of Dotfriles

My fork of Dotfriles adds the following features:
 + Mac OS X support, including Homebrew for package management
 + SublimeText 2/3 support, including copying config files to the Correct Place on OS X and Linux
 + Ability to install packages from a list in `~/.dotfriles/packages.txt`

Please sanity-check my additions before merging :)
I'd prefer that the merge-able Readme doesn't refer to this as a fork. Because if I approve this merge, my Readme will think I'm a fork of myself.
