Change steppe horde reform to by tech group instead of government

[balmung60]

This is not a request to change the "reform or die" idea for hordes, but rather to deal with situations in which taking the wrong reform means that you're stuck with "die".

Currently, it's possible to create situations in which a country is permanently stuck with horde units, but not the government. These situations include forming Byzantium and Westphalia and forming a colonial nation, all of which create a nation that has nomad tech, horde units, and a non-steppe horde government, meaning that they can't reform. Also, I'm sure the converter can manage to contrive a few more situations.

The way I see it, there are two solutions here. First is to, like in many past cases and as Crash Course World History is fond of saying about the Mongols, make an exception - no CNs, Byzantium, or Westphalia formation for hordes. This would work, but it's a relatively crude decision, especially in the case of colonial nations.

Second is to slightly rewrite the reform decision to be by tech group instead of by government.

This is basically a change to the current decision and should more or less work for every situation.

	steppe_horde_reform = {
		major = yes
		potential = {
			technology_group = nomad_group	#By technology group instead of by government
			OR = {
				ai = no
				full_idea_group = economic_ideas
				full_idea_group = innovativeness_ideas
				full_idea_group = administrative_ideas
			}
		}
		allow = {
			adm_power = 200
			OR = {
				legitimacy = 90					#For monarchies and normal hordes
				republican_tradition = 0.90			#For anything that managed to become a republic, including colonial nations
				government = theocratic_government	#For anything that managed to become a theocracy
			}
			stability = 3
			OR = {
				full_idea_group = economic_ideas
				full_idea_group = innovativeness_ideas
				full_idea_group = administrative_ideas
			}
		}
		effect = {
			if = {
				limit = {
					NOT = { tag = TIM }
					NOT = { tag = MCH }
				}
				swap_free_idea_group = yes		#keep progress
			}
			add_adm_power = -200
			add_stability = -5
			if = {
				limit = {
					government = steppe_horde
					}
				change_government = despotic_monarchy		#Keep the current government change where applicable
			}
			if = {
				limit = {
					technology_group = nomad_group
					NOT = { religion_group = eastern }
				}
				change_technology_group = muslim
				change_unit_type = muslim
			}
			if = {
				limit = {
					technology_group = nomad_group
					religion_group = eastern
				}
				change_technology_group = chinese
				change_unit_type = chinese
			}			
		}
		ai_will_do = {
			factor = 1
		}
	}

The only thing I can think of is that maybe it should be easier for a nomad tech colonial nation to reform if their overlord has already reformed.
