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

(cherry picked from commit bd8e5bf5)

added functions to create global waypoinst, modifying the WaypointList class, MapWidget and MainWindows.
