Update v1.01

Patch notes: Fixed incorrect purchase cost on barrier 6. Fixed ammo not dropping or giving too much ammo. Fixed melee causing AK47 to go invisible or glitch out. Fixed and balanced AI only being two shot but increasing in number until wave 16. Waves should be able to progress further now.

Added content: Added two new perks; Atomic Nexus, a domain that fries robots who enter the barrier and Bite Back, a damage increase perk that multiplies your damage 4x!
