Added a check for a division by zero in AbstractCalibrator::logAverage(). This was causing a crash when attempting a calibration when there's no RC data being received.

Fixed canceling the Logging function through the button on the main toolbar

Added text (component id) to cone/circle symbol symbolizing pose data from that component in 3D view.

Unified all object selections in 3D view via right-mouse-click, and added mouse-based terrain translation/rotation.
