Merge pull request #125 from KayenEQ/master

Added lower bounds for chance of charm fading.
Melee Crits, HoTs, DoTs messages should now filter correctly

Clients that also support seeing others DoTs will now see them

    Note: HoTs 'mine only' doesn't seem to be different from 'show'
Implemented deadly strikes and increase rogue throwing crit rate

New rules:
	Combat:RogueCritThrowingChance, Combat:RogueDeadlyStrikeChance, Combat:RogueDeadlyStrikeMod
Rogue throwing crit rate is rather ridiculous. These rules might need tweaking
but they gave me fairly live-like results, even with AA added
Optimized EntityList::AddHealAggro
Root spell revision
Optional SQL
