*really* fix instrument triggers
...
last commit was completely wrong. also i read somewhere that the
instrument alone doesn't reset volume, which is apparently a lie.

fix triggering without note

you can retrigger a note just by using the instrument column.

- 8-bit samples were sometimes being loaded with an offset of -1, eesh,
no wonder i had to work so hard to eliminate clicks and pops

when there was no panning envelope, panning was totally wrong
panning is still sort of wrong, in that the RMS power of a channel is
not constant over pans...

IT WORKS!
...
fixed many, many bugs, implemented playing (should be relatively
efficient), volume envelopes (but not panning envelopes). found that
instruments start at 1, not 0, and note C-0 is 1, not 0... so it is now
in tune with FT2!
no effects are supported at all yet, and there's a bug where it stops
playing entirely for a while, but "my dirty old kamel" sounds
recognizable and in tune!
