has_discovered		has_discovered =	tag/THIS	Returns true if the current province has been discovered by the target country.
nationalism		nationalism =	????	MUST CHECK. I guess this might be one of two things: it expects a number and will return true if the RR due to nationalism is at least that in the province, or it expect a yes / no and will return true if there is nationalism in the province. I’d bet on the former…
tolerance_to_this		tolerance_to_this=	????	MUST CHECK. I guess this might expect a number and will return true if the tolerance for the province religion is at least said number. But it might be an entirely different thing… even a country trigger.
