Allow Adjacent Settlements
Removes the restriction forbidding the placement of settlements adjacent to each other, and now also comes with the option to disable the relationship penalty from settling close to another faction's settlement.
I have a slightly better idea of what I'm doing than when I made the initial version so for 1.4 I redid the patch to use a transpiler instead of a postfix, and it seems to work. It's probably compatible with anything else that doesn't touch the conditions for creating settlements.
