Merge branch 'master' of https://github.com/mavlink/qgroundcontrol into Airmap

# Conflicts:
#	qgcresources.qrc
#	src/FlightDisplay/FlightDisplayView.qml
#	src/MissionManager/MissionController.cc
#	src/MissionManager/SurveyMissionItem.cc
#	src/MissionManager/SurveyMissionItem.h
#	src/PlanView/PlanView.qml
#	src/QGCApplication.cc
#	src/Settings/AppSettings.h
#	src/Vehicle/Vehicle.h

Note that SurveyMissionItem (.h/.cc) was changed in such a way that all previous changes were lost. Dynamic computation of its bounding box is missing and needs to be added into whatever is now handling these.
