Big set of Warlock Changes

Blizzard finally recognized the problem and it was the negative resistance thing.

Basically, the summary is that they're putting ruin back to 100% bonus, but in 1.9 they're changing the resistance debuffs to not go below zero, but they will also add the ability to increase damage to the target a little bit. It'll bring down the amount that the damage is increased when using the spell (since there won't be any of those double base damage crits), but will still make it usefull across a variety of targets.
