	Different invasion types can be definied with different mobs (devil, undead, milygo, ...)
	When you introduce a new type you must create the correspending regen.txt in the 
	locale/_master/map/mob_invasion/mobs_regen_MAPID_ file
	The file must be created and named:
	mobs_regen_[MAP_ID (1,21,41)]_TYPE_WAVE.txt
	
	An Event have 3 different waves. A wave means spawning from one kind of mobs
	The idea behind:
	1 wave = low level mobs
	2 wave = aggro mobs from the same type
	3 wave = Boss from the mob type
