Visual mode, UDMF: control line's OffsetX and OffsetY were not taken into account when calculating texture offsets of 3d floors' sides.

Fixed: textures defined in TEXTURES have higher priority in (G)ZDoom than images with the same name in "textures" folder.
Fixed another possible crash when MODELDEF is reloaded.
