* Updated MAP03 (by Mechadon)
* Updated MAP12 (by Saint_Guy)
* Updated MAP13 (by MinerOfWorlds & Mechadon)
* Updated MAP16 (by Mechadon)
* Updated MAP20 (by Mechadon)
* Updated MAP26 (by Mechadon)
* Updated MAP27 (by Mechadon)
* Redid SKY4/SKY4TALL so it looks a little bit better.  Also added a lightning strike animation for the tall version.
* Updated the MAPINFO to fix a few minor things (change skies, music, etc).
* The map names in the dehacked were updated so they have level numbers.
* Updated the Motherdemon's name in the monster casting at the end of the game.
= Fixed the sky for MAP27 in the MAPINFO so it uses the red/yellow firey sky, not the green one.
= Fixed the sprite offsets of the Motherdemon's last couple frames of death animation.
= Fixed the map names for MAP31 & MAP32 in the dehacked (they were swapped).
= Removed a duplicate SKY3 entry in the TEXTURE1 lump.
!! MAP01 does not have COOP starts.
!! MAP02's blue key trap is slightly buggy in that one of the switch hallways will use the wrong flat transition if it is picked to be the "correct" hallway (should be water if its correct).  This whole setup is really tricky so I don't know if I can fix it.
!! MAP05 has a non-COOP Nightmare Cacodemon which should not exist (just need to swap out the gore object).
!! MAP31's 3-key exit does not exit to MAP32.
!! MAP32's music doesn't loop in Chocolate Doom.
!! MAP33 has some massive SEGS overflows.  Also the sky doesn't look great in it because you can see way under the horizon at the start.  I don't know if this should be considered a problem or not though...
!! The warping fire skies don't tile properly in ZDoom's software renderer for some reason.  Might be a bug, but this can be reverted if there's no way around it.
