Direction Specific Pathing for buildings

[erdrik]

This is less a suggestion for a specific building, and more a suggestion for a function that can be turned on for certain buildings(existing or future buildings).

The idea is that the building can be walked onto or off of(like solar panels and tables), but only from one or more specific direction/s. This could allow for things like thin walls where the wall visual is on the edge of the tile, and the pawn can walk on the tile but not through the wall, or floors/bridges with railing to make one direction pathing, ect...
