- Added some simple translucency map analysis for BOOM maps to more

intelligently pick the value to use for TranslucentLine's second argument.
- Added a queryiwad_key cvar to control which key can force the IWAD selection
  to appear. It can be either "shift" or "control". Any other value will
  disable its functionality.
- Fixed: A_SkullPop() and A_FreezeDeathChunks() did not transfer the player's
  inventory to the new dismembered head "player".
