first divine gift artifact (trunk only)

first divine gift artifact (trunk only)

     From the newsgroup:  if no co-aligned artifacts are available when
attempting to give the first divine gift for an offered corpse, nothing
would be given.  Since the gift counter stayed at 0, subsequent attempts
to select one would still treat it as first gift and always fail again.

     The first divine gift from offering corpses must match the hero's
alignment; after that, nonaligned artifacts (Frost Brand, Giant Slayer, &c)
are added to the pool of choices for further divine gifts.  It's pretty
easy for a chaotic character to use up the co-aligned artifacts before
getting any divine gift.  There aren't many chaotic ones and some are
inelgible due to being race-specific items.  Wishing for Stormbringer--or
loading a bones file which contains it--and creating Sting and Orcrist
via naming will do the trick for an elven hero.

     This patch expands the pool of candidates to include nonaligned
artifacts during first gift selection if no co-aligned ones are available.
