Switch to more compact form of output for bool.
...
This also will hopefully deal with GCC's slightly confused claim that 'value' may be used without having been initialised down at #define OutputIntC (i.e. after it's out of scope, but I can sort of see why GCC might get confused while it remains in scope).

I guess next I need to get ADSR/volume in general working, before I can go FM? Then I'll worry about using the proper log-sin/exp tables.

Splits OPLL and OPL2 classes.

Logic is: they have different mixers (additive in the OPL2, time-division multiplexing in the OPLL) as well as different register sets. So I'll put operator and channel logic directly into those structs.
