Here is the last test binary before next release.

Main loop timer code has been redone making it easier to add more timers in the future and X is polled every 250ms when a button is down. This doesn't fix the problem with X not waking the main loop immediately for some button up events but the continuous polling should significantly reduce time from tap to action. Let me know if this new code screwed something up.

- Swiping from button bar to widgets will work better now
- Fullscreen clock now requires a downward swipe to close
- Long press is required to open governor dialog
- Volume and brightness sliders can now be dragged
- Process viewer is now updated while being scrolled with finger

The code to set brightness is cpu intensive and can't track like the volume slider does.
