Most of the stuff that was in main(...) function before directly is
related to creating a new instance of ZynAddSubFX master class,
therefore moved initialization and shutdown code into constructor
and destructor of RemoteZynAddSubFX class. Should have no functional
impact.
The shutdown code was extended to properly destroy the ZynAddSubFX
instance.
