[v18.3 HF2 soviet tiles submap]

This is the last build that gave access to the tiles for the submap editor.

A lot of the soviet submap tiles are out of position and cant be used without editing the position.

Most major issues have been with soviet double doors in tiles/soviet/factory

double_door_sw_empty +nw+ne+se

double_door_sw_open +nw+ne+se

gate_l_open_ne

gate_l_empty

gate_l_open_se
