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.

Put libraries into one libs directory under qgroundcontrol. Changed the neccessary files with references to those libraries.

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

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
