* options.h, main.h, keygen.c (keygen_set_set_prefs, keygen_get_std_prefs,

keygen_upd_std_prefs), keyedit.c (keyedit_menu), g10.c (main), pkclist.c
(select_algo_from_prefs): Add --personal-preference-list which allows the
user to factor in their own preferred algorithms when the preference lists
are consulted.  Obviously, this does not let the user violate a
recepient's preferences (and the RFC) - this only influences the ranking
of the agreed-on (and available) algorithms from the recepients.
Suggested by David Hollenberg.

* options.h, keygen.c (keygen_set_std_prefs), g10.c (main): Rename
--preference-list to --default-preference-list (as that is what it really
is), and make it a true default in that if the user selects "default" they
get this list and not the compiled-in list.
