What does this pull request do?

• TakeSwipeLungeDamage should be CBattleEntity type for Attacker, changed from CCharEntity.
• CalculateBaseTP had signature mismatch between defined/declared (Declared: int, Defined: int32) for delay. Changed all to int32.
• Removes declaration for undefined function: CheckMobMultiHits

Steps to test these changes

• No errors with mob type calling TakeSwipeLungeDamage should occur
• No other impact to gameplay
