Qt "Paper Doll" inventory

Enhance the "Qt Settings" dialog box to provide control over the
paper doll subset of inventory displayed between the message and
status windows (above the map).  A ton of flailing about for a
fairly small but useful change in functionality.

Old dialog (no title):
| [ ] Zoomed            -- check box
| "Width:"  [      ]    -- number entry spinner
| "Height:" [      ]    -- ditto
| "Font:"   [      ]    -- Huge:18pt, Large:14, Medium:12, Small:10, Tiny:8
| [      Dismiss      ] -- button

New dialog:
|     "Qt NetHack Settings"
|
| "Map:"    [ ] "Zoomed"        -- check box
|           "Tile Width"   [  ] -- number entry spinner
|           "Tile Height"  [  ] -- ditto
| "Invent:" [ ] "Shown"         -- check box
|           "Doll Width"   [  ] -- number entry spinner
|           "Doll Height"  [  ] -- ditto
| "Font:"   [      ]    -- Huge:18pt, Large:14, Medium:12, Small:10, Tiny:8
| [          Dismiss          ] -- button

The inventory subset can now be suppressed.  When shown (the default),
its size can be set independently of the map tiles' size.  I've set
the default to be 32x32 tiles instead of 16x16 used for the map.

The settings are saved and restored automatically by Qt, and persist
not just across save/restore cycles but into new games.  (That's not
a change, just a reminder.)
