0.2 almost ready for release!

I'm really close to releasing version 0.2 of ArduinoRCLib! This release will add Servo signal input/output and PPM input. These are the building blocks you want when you're interested in building a receiver or a flight controller. They allow you to easily read data coming from a receiver and control servos, for example.

Quite a few bits have been refactored, the use of Timer 1 for example, and the use of normalized values vs microseconds.

All that's left to do is double check whether everything is still functioning, so expect a 0.2 download within the next 24 hours, or check out the SVN repository if you can't wait ;)
