Fixed data stream interface widgets - now transmitting after 400 ms user timeout. No more data stream request flooding

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
