Reset justpicked only when picking up items

Browse Source 
With reset_justpicked called unconditionally near the top of pickup, it
was impossible to pick up some items, walk over to a chest, and use 'P'
to deposit the items with autopickup on: pickup is called with every
move, and autopickup allowed execution to reach the reset_justpicked
call whenever the hero stepped on a square with an item in it.  As a
result, stepping onto a square with a container would clear all the
justpicked flags in inventory (pressing ',' and then declining to pick
anything up would have a similar effect).

Instead, call reset_justpicked only when the hero (or autopickup) has
actually selected an item to pick up.  This makes the code a bit more
complicated than before -- I don't think there's a way to do it with
just one reset_justpicked call any more, due to the structure of pickup
and the need to call reset_justpicked before actually putting any items
into inventory -- but it means that justpicked info will be much less
ephemeral and more useful when managing stashes, etc.
