Gate wall patch

[PantherX]

Not sure if this is a complicated request but it would be awesome if the wall_patch property of the gate entity could be specified directly in the wall entity prototype (similar to how wall_diode_green and wall_diode_red are specified in the wall, rather than the gate). This would allow for custom wall entities that patch the gap between the gate and the wall using custom sprites rather than having to create entirely new gate entities for each type of wall.

I noticed this is now implemented in 0.17 through the gate_connection_patch property. Thanks!
