Performance boost (exponential) - Adjusted default idle cast check timers in rules

Browse Source 
- NPC:NPCToNPCAggroTimerMin	500 (Now 6000) 6 seconds
	- NPC:NPCToNPCAggroTimerMax	2000 (Now 60000) 60 seconds
	- Database version 9089 will take care of this update automatically only if you used the default values
	- The CPU cost of NPC's checking the entire entity list to cast beneficial spells (Heals/Buffs) becomes extremely high when
		higher NPC count zones exist (Based off of process profiling)
			- Distance checks for every single NPC to every single other NPC who are casting beneficial spells occur every .5 - 2 seconds unless
				npc_spells dictates other values, which most of the time it does not
	- Zones that once fluctuated from 1-8% CPU with no activity (Idle but players present) now idle at .5% based on my testings due
		to this change in conjunction with the past few performance commits, these are zones that have 600-800 NPC's in them
	- These values normally are overidden by the spells table (npc_spells), fields (idle_no_sp_recast_min, idle_no_sp_recast_max)

Akkadius: Made many performance optimizing oriented code changes in the source
- Added Rate limit the rate in which signals are processed for NPC's (.5 seconds instead of .01 seconds)
