A couple of broken XG classes
A couple of broken XG classes:
It seems that the plane_move xg class crashes 1.9 Beta6 with a "SetValue: DDVT_PTR incompatible with value type DDVT_INT" error.
Also the wall_texture/material class seems in-functional. It doesn't crash 1.9 Beta6, but it doesn't do anything at tall.
