menustyle:full's 'A' choice

Change how menu choice 'A' (auto-select everything) works.  It will
now auto-select all things that match any other choices (object
class(es) or BUCX state(s) or possibly unpaid status).  So it still
skips the second menu of specific objects.  And it still picks all
objects when it is the only choice or if player uses '.' to select
it along with all the rest of the first menu's possibilities.

This change won't help anyone who picks 'A' without really meaning
to.  (Maybe add a paranoid_confirm setting to for full-menu-A?)

Affects container apply/#loot and Drop-multiple.  The invent.c part
is just formatting.
