Reverted bank and SoundFont ID queuing, now executed immediately using atomic instructions as previously.

Browse source 
Program number now uses 8 bits in the SoundFont ID/bank/program integer, where a value of 128 indicates an unset preset.
fluid_synth_unset_program() now causes preset to be unassigned until a program change occurs.
Updated units in documentation for fluid_player_set_midi_tempo().
