- Fixed: MugShotFrame::getTexture() allocated space for the sprite name that

it never freed. I'm not sure it's a good assumption that 9 characters is
  always long enough, either, since you can have longer file names than that
  inside a zip.
- Fixed: DSBarInfo::DrawGem() crashed if chain or gem was NULL.

 - The listener's velocity is now set at 0 for the sound engine. The player
