I made a simple change to descr_strat to unlock the unlockable factions (not the unplayable factions).

The beginning of descr_strat should be changed to this for it to work:
Code:
campaign		imperial_campaign
playable
	england
	france
	hre
	spain
	venice
	sicily
	milan
	scotland
	byzantium
	russia
	moors
	turks
	egypt
	denmark
	portugal
	poland
	hungary
end
unlockable
end
nonplayable
	papal_states
	aztecs
	mongols
	timurids
	slave
end
Its pretty simple as you can see, just got to make sure you don't upset the position of the code lines (eg. nonplayable, end).
