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

Fix for crash when removing item from QuickView, and addition of more generic signal/slot combonation for property updates

Added satelliteCount to the QuickView, and made quickview a default display on the mission planner view.

Change so mission view is default instead of unconnected, fixing a bug causing misloading of tool widgets

Additions for View navigation, including saving dockwidget locations and status. Also added remembering of "Advanced Mode" between restarts of QGC

Changes for the new "View" navigation, and fixes to get most of the dockwidgets working with the new view system
