Qt extended command selection

Browse Source 
Simplify extended command selection under Qt by allowing the
autocomplete subset be one of the choices for its [filter].  That's
the same subset as X11 uses, where #q is unambiguous for #quit
instead of competing with #quaff and #quiver.

Unlike under X11, the player can use [filter] to switch to the full
command set and get access to a few commands which have no useable
key and aren't flagged to autocomplete.  (Mostly obscure wizard mode
commands but #exploremode is in that situation.)

In normal and explore modes, the [filter] button just toggles between
two sets of commands (all normal mode commands vs autocomplete normal
mode commands).  In wizard mode there are four choices and you might
need to click on [filter] up to three times to step through to the
target one among four sets (all commands, all normal mode commands,
autocomplete commands for both normal and wizard, full subset of just
the wizard mode commands).
