HIL config improvements, fixed confusion about which dock widget is part of which view, main window behaving now

Hotfix: Fixed widget / UAS initialization order which led to text messages (and other updates) being ignored if the widget was not open when the UAS was created

Added missing separater to Tool Widgets menu.

Changes for new calibration in APM 3.0 (Re: https://github.com/diydrones/MissionPlanner/issues/38), and change in some of the serial timeouts

Addition of requesting status updates from APM, if APM is in a state with no status updates, this will request them

Change so Waypoints are the same across maps, and offline waypoints get appeneded to the end of the MAV's waypoint list on connect

Started adding numbers to QGC_APPLICATION_VERSION for development builds, since dev builds need the config file wiped out for UI changes to be visible
