I added the ability for the parser to pack an array of any mavlink standard type.  This will allow array types to be specified for mavlink messages without using the type="array" syntax.

I also changed how a bunch of the strings were constructed to more closely conform to the coding style guidelines by reducing the number of implicit copy constructor calls

Changed NUM_OUTPUT_SIGNALS to an const unsigned short from a #define and moved its definition into OpalRT.h from OpalLink.h so that the configuration would all be in one place.

OpalLink should now be able to be disconnected.  I also added a test to see if params had already been allocated before calling new in OpalLink::connect()

Working on QGraphicsView-based local waypoints interface supporting drag-and-drop, commented code, fixed Google Maps interface, added mouse and SpinBox zoom to HSIWidget, fixed MAV-based coloring and stylesheets - MEGA COMMIT

Cleaned up communication structure significantly, should now be easier to add new links. Signal bytesReceived(link, QByteArray) is now only way to pass on newly received data

Added MAVLinkLight as an example how to add new protocols, it is currently not an actual implemented protocol

fixed mutex usage in getTotalUpstream and getTotalDownstream and added initialization to connectionStartTime
