PatR 2b1f8a1b43 fix #K166 - role selection filtering ...

pick_role() had a 5 year old copy+paste error where a pair of lines
were cloned multiple times but one of the resulting lines didn't get
the intended revision, preventing OPTIONS=align:!chaotic or !neutral
or !lawful from working as intended when letting the game choose role
randomly.  The bad line should have been calling ok_align() but that
routine turned out to have a bug too.

Fixing those lead to other less obvious problems with role selection,
particularly the tty menu version for picking manually.  Roles and/or
races which should have been excluded by partial specification weren't
always kept out.  Also, if any filtering was specified, trying to
disable all filters (via choosing 'reset filtering' and de-selecting
everything in the menu) was a no-op.  Once any filtering was in place
you had to leave at least one role or race or gender or alignment
flagged as not acceptable in order to change any of the filtering.
When that was fixed and it was possible to turn off all filtering,
there was no way to turn it back on because the menu choice to reset
the filters wasn't offered unless there was some filtering in place
(that was intentional but turned out not to be a good idea).

I checked curses and X11; they both offer less versatile selection
capability that don't seem to need the tty-specific fixes.
