About wavetools.audio 2.1:
Replaced a SendIO with a DoIO in replay routine (hard work :)
Also added input gain (or rather I activated it since almost all the
code was in there).

It works fine on my A4000/040 for replay using delitracker 2.27.
I tried gain with The harddiskrecord program for AHI distribution.

Problems:
Wavetools has only 16 levels of input gain ranging from 0 (no gain) to
15 (22.5 db gain).
Fixed bug in inputgain now it should work as it was intended.

About wavetools.audio 2.11:
Misunderstood how inputgain worked, but now it should be fixed.
