Game server/skill system: HoT's are now also displayed client side.

Furthermore, they don't have a cooldown according to the TBLs, the
database and knightdb.info (Past restore does have a cooldown, which is
being triggered appropriately now)
BUGFIX : Pretty sure this was intended to do this rather than the previous

Could've caused some bugs, not sure if it did.
BUGFIX: Same as last one, just incase there was some intended behaviour being changed arbitrarily.
BUGFIX: AoE's will now go on cooldown, also allowed for stackable debuffs

NOTE: Not sure about the stacking of debuffs / overwriting of debuffs,
if need be we'll need to provide a workaround. Fixes
