Ivan Savenko edb2ecd751 Fix possible overflow errors on leveling up beyond int64_t limit
- added separate giveExperience method instead of weird changePrimSkill
- experience is now always used in form of int64_t
- max supported level reduced from 201 to 197 to fit into int64_t
- fixed undefined behavior in experience calculation
