Moved Debuff handling to Combat + Bugfixes

* Majority of mob debuff handling is moved to combatStep().
* Drain now kills the mob and does 40% overall damage.
* Bumped up active nano debuff durations, debuffs like drain linger longer but damage less.
* Debuffs are cleared upon mob death and retreating.
* Patched out vehicle off success packet spam
* Boosts and potions now cost the right amount (100 taros) and give the right quantity (100).
* Damage was tweaked slightly. At higher levels you are more likely to fall prey to rand().
* Enemies now use run animations during combat and retreating.
