OP-1122 OP-1123 fixed OSX specific GCS compilation errors
OP-1122 OP-1120 Added a new FligthPlanInfo uavobject
- FligthPlanInfo contains the number of waypoints and action pathes
- FligthPlanInfo contains a CRC of all waypoints and action pathes
- The CRC is not yet implemented
- These informations will be used to check the consistency of a flight plan
OP-1122 OP-1145 made ground uavtalk code more similar to its flight side version
OP-1122 OP-1120 moved CRC8 utility from uavtalk.cpp to new utils/crc.cpp
