- Guild Castle code cleanup:

  - all changes to guild castle data are now handled first by map-server and only sent to char-server for saving
  - ensured that changes made to guild castle during char-server disconnection time will be resent on reconnect
  - actually removed definition of `MAX_GUILDCASTLE` (r15657)
