TODO

• Make ZSH/Bash PATH dynamically figured out (via globbing) like fish
• Make rake install install a .git pre-commit hook to remind about or automatically remove all API keys from dot files (gitconfig, etc)
• Make rake install set up a loop that will always try to git pull the dot-files (if working directory is clean) so they are always up to date
• Remove 'export' from variables that don't need them
• Make current directory red in prompt if non-writeable (ala fish)
• Fix shell $PATH. Intelligently build up from only existent directories and ensure no-duplicates
• Steal some awesome stuff from https://github.com/skwp/dotfiles/blob/master/osx
