* 'master' of git://github.com/BaxterStockman/dotfiles:
  Added vimrc function that allows aliasing to builtin commands
  New timeout -- 150ms was too little.  250 seems about right.
  New bindings for directional keys in tmux.conf, and shorter timeout for repeatable actions
  Revised bin/dotfiles for better initialization
  Changes to .vimrc settings.  Now autoloads new settings on writes to configuration files
  Moved tmux autoexecution script earlier in /source order
