Removes the open dialog code that runs when no arguments
are supplied with QEMU. Not everyone needs a hard drive
or cdrom to boot their target. A user might only need to
use their target's bios to do work. With that said,
this patch removes the unneeded open dialog code.

Add a dialog box that tells the user to start QEMU from
the commandline instead of the Finder.
