Various bugfixes and adjustments

* Nano missions should now stop repeating.
* Bitwise operators are now used to handle buff/debuff bitfields.
* Changing nano powers will no longer grant you infinite buffs.
* Mobs now heal up client-side after retreating, this comes with candy effect being played however.
* Lower level mobs now hit harder.
* Nanos drain stamina quicker when they grant passive powers.
* Healing, damage and leech powers scale up with your level.
* Player on player damage now accounts for damage and armor.
