- Fixed: The C code in AltSoundRenderer::CopyAndClip() did not shift the sample

data enough (2 bits instead of 8), so it was super loud and aliased.
- Fixes for GCC 4.1: Several type-punned pointer warnings, but more
  importantly, declaring a friend function inside a class body is no longer
  enough to declare that function globally; you must declare it again outside
  the class.
- Upgraded FArchive::SerializePointer so that it can store 32-bit indices.
- ACS printing pcodes now build their string in an FSttring instead of a fixed
  sized buffer on the stack.
