fb56b02041 Modify the bsinc resampler 
Readjusted the bsinc12 cutoff back to -60dB. Also increased the filter's phase
count.

882b4acae8 Add "fast" variants for the bsinc resamplers 
This simply omits the scale factor from the filter, similar to how up-sampling
does. The consequence of this is less smooth transitions when ramping the
pitch while down-sampling, but otherwise behaves fine.

9b64e5e0db Implement a "fast" bsinc path 
This takes advantage of the fact than when increment <= 1 (when not down-
sampling), the scale factor is always 0. As a result, the scale and scale-phase
deltas never contribute to the filtered output. Removing those multiply+add
operations cuts half of the work done by the inner loop.

Sounds that do need to down-sample (when played with a high pitch, or is 48khz
on 44.1khz output, for example), still go through the normal bsinc process.

3154a915b1 Remove the ReverbSpeedOfSound hack 
No other effect depends on context or listener properties, so reverb being the
only exception for speed of sound and meters per unit was putting extra work on
the effect engine for no real reason. Especially since the reverb decay time
should be the time actual time to decay irrespective of other settings.
