Add map type selector menu; use Bing maps by default; zoom to a more
human scale on Go Home

Fix for static const float cannot be initialized within a class definition, and other windows compile errors.

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

The right click menu will only show up when connected to an APM autopilot,
since this feature is APM only.

X-Plane HIL proven both ways, data conversion and controls feedback set up correctly, needs actual HIL flights tests now

Also removed redundant code in QGCMapWidget.cc.

Finally resolved waypoint positioning issues, 2D and 3D map work now nicely together with less flicker

Significantly improved logging precision, added hole filling for missing data points (user-preferences for this still pending)

Improved map caching, waypoints and lines now colored with UAV colors, debugging map drag / zoom issue with waypoint lines

Map caching works now, uav following as well. Waypoint lines and some graphical tweaks needed, but its very close to an alpha release now

Runtime issues resolved, quick application startup and good runtime stats: 0.3% load in idle mode, 15% load showing map and UAS list. Map has a zooming issue, but should be resolvable

Working WP manager -> map waypoint updates. List reordering does not work yet. Next steps: List reordering, map -> WP manager updates, better waypoint graphs
