chown: cleanup and tweak

- update help text to standard syntax
- streamline duplicate code
- remove unnecessary param count checks
- remove explicit nil check where not needed
- updated locale to be neutral to admin or owner
- don't call get_owner or valid_password if is admin
- remove core.player_exists() call since target was checked when joined
faction
- abort early if no target or password provided
