Compositor: Add resetOrderOffset()

Browse Source 
To allow for custom compositors and passes created by C++ code alongside
those created by Compositor::create(), add a resetOrderOffset() function
which resets _order_offset back to zero. This will allow FlightGear to
prevent repeated compositor reloads from increasing _order_offset
indefinitely, which soon results in render orders beyond those set
statically for the GUI and upcoming VR mirror compositors.
