This is exactly where we Windows-ites want it to appear.

This needs to be done at compile-time, and it's done using the resource
editor for the Windows compiler.  I don't know how the Mac and X handle it.

For Windows, we may not need this.  Creating an icon with the
IDI_APPLICATION identifier does make the icon appear in the desired places;
the problem is that calling set_)window_title seems to clear the icon.  Does
anyone with experience in the Windows guts of Allegro know how to keep
set_window_title from clearing the icon?
