TrackerCommand --> MeasureCommand + fuse against exception in MeasureTool dtor + added DeleteMeasureCommand + moved the various concrete measuring tool-related classes to their pre-assigned file locations (everything was crammed into MeasureCommands.* files up to this commit) + added double-click handler to GuiAdapter (for TOA implementation of "delete measuring tool on double-click")
