Added features:
Menu items to switch floppy and CD image files.
Menu items to eject floppy and CD image files.
Menu item to use /dev/cdrom.
Verifies with the user before quitting QEMU by displaying a dialog box.

Added yellow background to the pause label.
Removed all depreciated methods.
Using strncpy() in place of strcpy() in emulatorHasDevice() .
Eliminated all warnings when compiling.
