Mosquito Kingdom annex

[rogerburks]

I ran into a immersion issue with occupy_miskito that is specified in USCA.txt. Even if you have an independent Mosquito Kingdom, with a good amount of places taken over, Nicaragua can still annex you by event. I think there could be an issue with the allow statement. I changed the following is_vassal requirement (under MSK =) from no to yes to fix this, and I suggest that this become an official change. Reason: an independent and potentially strong country (as it was in my playthrough by the time that Nicaragua gained the proper requirements) should not be annexed-by-decision by a much weaker one. Maybe there is a more elegant solution (such as requiring a war to annex an independent MSK).

	allow = {
		war = no
		is_vassal = no
		revolution_n_counterrevolution = 1
		MSK = {
			OR = {
				vassal_of = THIS
				**is_vassal = no**
			}
		}
	}
