Use akracun's tmux and vitality.vim

This makes it so I don't have to run in bracketed paste mode always in
order to get cmd+v pasting to work in vim. Now it'll just work in vim.

This also enables FocusGained and FocusLost events in tmux, so you can do with
those as you please.

Of course, none of this works w/o building and using akracun's tmux.
Some reformatting
do not wrap for tmux, use tmux's bracketed paste mode instead
apparently tmux added bracketed paste mode

so I didn't need any of this crap. Sigh. Needs tmux 1.7 or greater
Add matchindent.vim to guess indentation settings
Some cleanup.

Sorry to those of you downstream if it causes conflicts :/
Hilarious little hack to make ctrl+h/j/k/l work to switch to other tmux

panes
Add !
handle focus in focus out w/ powerline
add sleep for focus tracking

add some comments
Use vim-vroom fork to fix tmux focus race condition
Use matchindent.vim fork to get rid of error msg while bundle install
Use vitality.vim again, my fork this time.

Should be innocuous to normal tmuxes.
use pane title for tmux switch

we have more control over it and it makes it work while running
`:!whatever`
Add tmux side comment
Merge remote-tracking branch 'up/master'
