Remove instsamp hack
This change removes the need for the instsamp hack in instrument and preset zones. The sampleid and instrument generators are treated as any other generator and simply passed to the defsfont import functions. Those read the two generators and use the index to look up valid samples and instruments. Both generators are then reset to GEN_UNUSED again, just to make sure that the rest of FluidSynth doesn't get confused. But that might not be necessary.
