1) comparison singed and unsigned values
2) redundent includes
3) wrong constructor :-part field initilization
4) unused not-/*name*/-guarded args in template/virtual functions that not required like args.
5) explicitly list not implemented achievement types.
Also bugs fixed:
1) Drop wrong phase mask 0 check in WorldObject::InSamePhase.
2) ArenaTeamMember::ModifyPersonalRating incorrect work with move points in negative with infinity values in result.
3) ArenaTeam::SaveToDB code send uint64 value to string with arg format %u.
