Cstat (wall)

A bitfield for how to draw a wall, as well as a few flags for interaction. Add all together all wanted flag values.

Unused bits are NOT free for user programming, but are rather reserved for potential future EDuke32 features.

Not to be confused with sprite cstat.

If the wall has cstat 2 applied to it (CSTAT_WALL_BOTTOM_SWAP) than the bottom half's attributes are applied to the current wall's nextwall
