* Fixed a memory leak due to EngineFactory::Destroy() not doing it
as an actual destructor and just removing the engine instance from
factory stock and all instances allocated via EngineFactory::Create()
never got delete'd and thus their destructors never called. This bug
was evident while having many mapped instruments and querying the
instrument status via GET MIDI_INSTRUMENT INFO command, eating up
system memory very quickly and never let it go.
