Update to ZDoom r4129:

    Fixed: Hexen's Floor_RaiseAndCrush is not the same action as the one used by Doom and which was used by ZDoom before r4053. Restored the old code and gave it a new special 99:Floor_RaiseAndCrushDoom.
    Fixed: Strife's slow Ceiling_CrushAndRaise lines do no actual damage.
    Fixed translations of Heretic linetype's that perform Floor_LowerToHighest with an offset.
    Added compatibility option for Claustrophobia 1024, map 01.
