Doxygen

Repo Layout

README was added to doc directory with inforamtion on how to run doxygen. A mention to read the README in /doc for information was added to the main README in qgroundcontrol.

Unit tests compile and run but still fail 4 tests. Segfault fixed which was caused by colors list in UASInterface.h.

qgcunittest.pro now compiles and runs as long as run in terminal in projcts->Run Settings is unchecked.

Added a README to doc on how to generate documentation with doxygen. In main README, added a mention to check the REAME in doc.

Issue #68. Took out the check of component id == 200 in MAVLinkDecoder.c...

Uas checks

NMEA library and all references to NMEA have been removed.

fixed waypoints with APM

as long as the waypoint comes from the right systemID there is no
point rejecting it based on component ID. 

The current_partner_compid is also completely wrong in the code, so
checking it makes no sense anyway
