Make crosstabview honor boolean/null display settings 
psql's \pset display_true/false settings, added by commit 645cb44c54,
affect normal query output, but not \crosstabview.  As a result, boolean
values used anywhere in crosstab output were always shown as "t" or "f",
which is inconsistent.  Change \crosstabview so that the configured
values are displayed instead.

While at it, make \crosstabview print the \pset null string, if any, in
cells for which the query produces a NULL value.  Cells for which the
query produces no value continue to have the empty string.  This is an
oversight in the aboriginal \crosstabview commit, c09b18f21c.

Add a regression test covering all of this.
