more fixes for revised 'sortloot'

After some permutation of commands which displayed items, the 'd'
command presented a prompt with the list of letters scrambled (in
loot order or pack order rather than invlet order), so explicitly
sort when getobj operates.  Done for ggetobj too.

For menustyle:Traditional, ',' followed by 'm' presented a pickup
list in pile order even when sortloot was 'l' or 'f'.  That was an
unintentional change during the 'revamp'.
