Fixed @changesex issues on PACKETVERs that don't support per-character sex.

- Fixes bugreport:8504
  http://hercules.ws/board/tracker/issue-8504-changesex/
- Existing database entries with an incorrect per-character sex will be
  fixed automatically when the character logs in to match the account's
  sex, if the PACKETVER doesn't support per-character sex.
