Changes to setup script, zsh and tmux configs for OSX
Disabled automatic title updates in zsh
  Switched to vundle and updated for OSX
  --------------------------------------
+ Removed git submodules in favor of having vundle manage vim package
  dependencies.
+ Removed ad-hoc vim plugins and moved them to being managed by vundle
+ Added solarized colors for OSX
+ Broke deps file into multiple files, one for each package manager,
  since their names and handling are all at least slightly different
+ Probably broke some things for my Linux environments, but I'll fix
  that later.
