extended quest text formatting (trunk only)

Add questpgr formatting codes to support pronouns for leader,
nemesis, deity, and artifact.
  %lh -> "he" or "she" for leader; %nh for nemesis; %dh for hero's god;
  %li -> "him" or "her"; likewise %ni, %di;
  %lj -> "his" or "her"; and %nj, %dj;
H, I, and J modifiers yield capitalized form of same.
  %oh -> "it" or "they" for artifact (Eyes of the Overworld is plural);
  %oi -> "it" or "them";
  %oj -> "its" or "their"; plus capitalization with uppercase modifiers.
Also, %O yields shortened artifact name ("the Foo" in place of "the Foo
of Bar").  These provide support for terser summary lines, but can also
be used in the regular quest text passages.

     A couple of nemeses don't specify gender.  The random choices need
to be made early so that the leaders' messages can get them right.  This
chooses during role initialization and then uses that result once the
corresponding monster is eventually created.  It does the same for leader
even though no current leader needs it, and for deity too.
