- Fixed: When note_on() is called and another copy of the same note is

already playing on the channel, it should stop it with finish_note(), not
  kill_note(). This can be clearly heard in the final cymbal crashes of
  D_DM2TTL where TiMidity cuts them off because the final cymbals are played
  with a velocity of 1 before the preceding cymbals have finished. (I wonder
  if I should be setting the self_nonexclusive flag for GUS patches to
  disable even this behavior, though, since gf1note.c doesn't turn off
  duplicate notes.)
- Changed envelope handling to hopefully match the GUS player's. The most
  egregious mistake TiMidity makes is to treat bit 6 as an envelope enable
  bit. This is not what it does; every sample has an envelope. Rather, this
  is a "no sampled release" flag. Also, despite fiddling with the
  PATCH_SUSTAIN flag during instrument loading, TiMidity never actually
  used it. Nor did it do anything at all with the PATCH_FAST_REL flag.

- Fixed: wbstartstruct's lump name fields were only 8 characters long
and not properly zero-terminated when all 8 characters were used.
