* clean up global variables in display.c, make one state variable* abstract case IO from display.c* Now that we use Xt, use a more modern file picker.* provide a simple case that doesn't need Xpm.* support session management* Documentation needs to be updated.* Port to cygwin32.  That would be cool as xcopilot's ancestry is in win32.* Use automated CPU build stuff from latest UAE dist.* use drag and drop* bare option with no case graphic.  Suggested by Malcom Herbert.  Apparently  the Windows version has this.* From Max Okumoto:   * Create cradle.xpm   * Modify code so when you use the -serial flag and the     port is a pty the cradle appears.  In addition handle     someone pressing the hotsync button.
