[1.2.276] More rebalancing

Patch notes on SW make this patch suck less for DrKs:

- Beholder's buff can now determine whether each users' pre-applied buff is better than beholders or not in order to avoid canceling pre-applied buffs if they are better than be holder's. However, if beholder's buff is better than the pre-applied buffs, the pre-applied buffs will be canceled and change to beholder's buff.
