Update to revision 722a9d6aaf5fb9b98bd3bdf12b8db2049cf129b7 (+3)

Bugs:
- Fixed inability to change faction leaders/2IC (#3792)
- Fixed inability to claim drops from npcs and creature (#3788)
- Fixed missing entity of member of faction check in IFF (#3789); note that your faction is now friendly by default unless you add an enemy rule

This was a bug-fix-only sync targeting a couple of blocking issues/major regressions that were affecting players after the IFF changes and introduction of hostile NPCs.
