OSX X11 defaults

Here are some changes to the X11 defaults I made on my Mac OSX.

X11 2.4.0 - 2.4.0 release notes
Close X11 if no other X11 apps are running

defaults write org.x.X11 wm_auto_quit -bool true
defaults write org.x.X11 wm_auto_quit_timeout -int 3

X11 < 2.4.0
Focus Follows mouse when multiple X windows are open. This avoids two clicks to activate a window:

defaults write org.x.X11 wm_ffm true
defaults write org.x.X11 click_through -bool true
