SDL 

- fix crash on OSX when removing a device. If the remove happened due to the CFRunLoopRunInMode call in SDL_SYS_JoystickDetect then we would delete the device right away, before SDL_SYS_JoystickUpdate could clean it up. So move the CFRunLoopRunInMode to after the cleanup logic, preventing this case. This does mean that adds and removes of joysticks now take 1 extra frame to show up.
