Michael Meyer 05f004403e Rename update_mon_intrinsics to ...extrinsics 
There was a TODO about this; not exactly a great challenge but it feels
like a worthwhile change since the name was misleading.  I also updated
the name of the do_intrinsics parameter of extract_from_minvent(worn.c),
since it was in a similar situation (and directly related, since it
controls whether to call update_mon_{in/ex}trinsics).
