Qt on OSX is inserting "Search [_____]" as the first entry in
the Help dropdown menu (the one in the toolbar at the top of the
desttop). While trying--and failing--to figure out how to get
rid of that, I cleaned up a little bit of the old menu hackery
(that tries to workaround the fact that Qt on OSX insists that
some menu actions--based solely on their names--should go into
the appication menu rather than whichever menu the program is
trying to insert them into). The only observeable difference
is that 'About NetHack-Qt' will be at the top (actually second
because of that Search one) of the Help dropdown, where it is on
non-OSX builds, rather than last.
This tries to make the program name consistent too, changing
several instances of "Qt NetHack" to be "NetHack-Qt". The latter
is the name being set up as ApplicationName in qt_bind.cpp that
gets used when Qt stashes the Qt-specific settings wherever it
stashes them.
It also makes another tweak in formatting of 'About NetHack-Qt',
inserting one explicit line break to avoid some poor looking line
wrapping. I still haven't figured out how to control that popup's
size.
