Added MAVLinkLight as an example how to add new protocols, it is currently not an actual implemented protocol

Started to add support for autopilot firmware updates, added Linux compile instructions, fixed date in mavlink.h to english independent of OS language settings

Added support for MAVLink XML inclusion, added support for multiple Autopilots, improved protocol generation

Pushed implementation of parameter settings, almost done. Added many new MAVLink messages needed for interaction with IMU

Switched from flite for speech on the Mac to built-in MacOSX speech synthesizer. Fixed build system for 64-bit builds (using official SDL.framework, and Qt frameworks).
