Adapt a useful scripted localisation

[Idhrendur]

NSB_soviet_scripted_loc.txt has

defined_text = {
	name = GetIdeologyNameWithCaps
	text = {
		trigger = {
			has_government = communism
		}
		localization_key = communism_noun
	}
	text = {
		trigger = {
			has_government = democratic
		}
		localization_key = democratic_noun
	}
	text = {
		trigger = {
			has_government = fascism
		}
		localization_key = fascism_noun
	}
	text = {
		localization_key = neutrality_noun
	}
}

which seems like it could be useful if properly adjusted for existing ideologies. Put it in a converter-specific file though.
