#restricted as bitmask - think about it!

[PvK]

(After whether or not IW feels like providing it,) what can be modded is the most important thing, followed by how easy it is for people to figure out.

Essentially we'd all like some way to have full control of which nations can use which pretenders, without having side effects and/or having to duplicate units to get around the unwanted effect of #restrictedgod.

Maybe there is another operation already in the game (from the programmer's perspective) which can be exposed by mod command, which would do the trick.
