resend: one desktop mode

Greetings all,
I sent this yesterday and I never saw it appear on the list, so I'm 
sending it again.  I apologize if you get this twice.

This is a first attempt at "fixing" desktop mode.  The Winelib program 
winedesktop creates and maintains one Wine desktop window that is shared 
across all applications.

How it works right now:
The winedesktop program, when started, attempts to register a window it 
creates as the desktop window.  If it succeeds, all Wine apps started 
from then on will be confined in its desktop window.  If there are any 
Wine apps running when winedesktop is run, it cannot become the desktop 
window because one already exists (the X root window).  If there are no 
Wine apps running, you can also say "winedesktop MyApp.exe" to start one 
in the desktop.  I tested this with several installers, and they all put 
the correct windows on top.  :-)  Apps can resize the desktop window, 
and the background bitmap is drawn if the appropriate entries are in the 
win.ini file.  The default size of the desktop is read from 
HKLM\Software\Wine\Wine\Config\x11drv, which probably should be changed, 
but that's where most users are likely to have it right now.

What doesn't work right now:
Any app that tries to run winhelp (pointing at a nonexistent help file) 
currently causes the input focus to get confused somehow.  The app is 
waiting for its SendMessage to winhelp to return, while winhelp is 
showing a modal message box that can't seem to get the input focus 
(although the message box is correctly painting its window).  Killing 
either the app or winhelp restores things to normal.

What maybe should be added in the future:
- support a full-screen mode, where winedesktop changes the real 
resolution to match its size and draws without WM decorations
- support multiple desktop windows and coexisting with managed apps

ChangeLog
- Moved management of the Wine desktop window to a separate process
