- Fixed: If an object is flagged for euthanization while it's in the gray

list, it should just be ignored during the propagation stage.
- After sleeping on it and realizing what was really going in, I generalized
  the inventory fix from the 13th: The actor is flagged by Destroy(), then it
  is later inserted into the thinker list by DThinker::SerializeAll(). So
  rather than unlinking the skipped player from their inventory, just make
  sure any flagged thinkers aren't inserted into a list.
- Fixed: FCanvasTextureInfo::Viewpoint needed a read barrier, and the whole
  list should serve as a root.
- Reimplemented SPC playback as a custom codec for FMOD.
- Removed spc_frequency, because snes_spc only supports the SPC's native
  frequency of 32000 Hz.
