---- Log message:

Cleanup fill_tile_sprite_array{_iso,}. This involves the removal of 16
variables like ttype_north or tspecial_north, removing superfluous
constructs like in "(ttype_north==T_MOUNTAINS ||
ttype_north==T_MOUNTAINS)" and the use of loops.

Patch from Jason Dorje Short <vze2zq63@xxxxxxxxxxx> with changes from
me.
