- added an option to disable reflective planes because they can cause

major slowdowns when used improperly.

Update to ZDoom r1306:

- Fixed: G_DoPlayDemo did not free the demobuffer or the CVAR backups when it
  failed to start the demo.
- Added a MF5_BRIGHT flag to always render an actor fullbright.
- Fixed: Calling Door_Animated with a non-zero tag created a new thinker
  for each two-sided line of the sector.
- Added Karate Chris's submission for making 'spray' a cheat.
- Added CO2's default parameter additions for several Doom code pointers
  submission.
- Added CO2's A_RemoveMaster/A_RemoveChildren submission.
- Added Blzut3's SBARINFO replacement for the Doom statusbar.
- Fixed: SBarInfo still displayed the wrong bar for height 0
- Added A_KillSiblings and A_DamageSiblings code pointers.
- added MaxAbsorb and MaxFullAbsorb properties for Armor.
- Restored the multiplayer scoreboard's former centering so that it doesn't
  look awful on widescreen intermissions.
- Fixed horizontal positioning of 'finished' on the Raven games when scaled.
