Qt status display

Move gold from in front of HP to the end of the line they're on,
and change its label from "Au:" to "Gold:".  That makes both HP
and gold easier to see, by having HP first and by having gold
be shown after a blank column (where 'Exp' was once displayed
separately from 'Xp').

Get rid of the obsolete 'exp' widget, replacing it with 'blank1'.
Used to force 6 columns for HP, Energy, AC, Xp+Exp, blank, Gold
so that the row lines up with the six characteristics above it.

Handle Blind the same way as all the other On/Off conditions
instead of setting its label dynamically every time status gets
updated.  The Qt3 code in outdated/ used to do things that way
and there doesn't seem to be any reason to have changed it.
Maybe someone (Ray?) had planned to show "Blindfolded" instead
of "Blind" when that's the only reason for being blind.

Reorder the widget declarations and initializations to match
their display order, and add a lot of comments.
