To prevent rendering samples for systems that are not in use.
Additionally, it gives the systems more flexibility to render the samples
according to their specific configuration.
the panning strategy for QSound has changed!
it's now 08xy where x is left and y is right (muting is not possible though!)
this makes it consistent with other chips, plus QSound's pan range was
32 anyway
in order to toggle the QSound effect use effect 12xx
this commit mostly rewrites the sample system.
as of now samples can be ADPCM, 8-bit, BRR or 16-bit
or something...
consider this VERY EXPERIMENTAL.
if you find any issues REPORT THEM immediately.
it's nearly 4am...
