The tmux conf from my mac
Just dumping in what I had in my tmux conf
Re-enable reattach-to-user-namespace

See the README in prefs on how to work around this on ubuntu later.
Disable global osx copy-to-namespace thingy
Finally fix osx vs linux tmux

Only load osx stuff on osx.
Better comment
Nicer colors in tmux, and larger scrollback
Faster window resize
