[Coco] MESSUI 0.154 with Becker port

[Guillaume Major]

Thanks to the work of Richard Goedeken, the MESS emulator now supports the 
Becker port interface for DriveWire. For those like me who prefer the 
Windows style menus, I compiled the MESSUI version for 32 and 64 bit.

Richard have added a new mess target 'coco3dw1' to emulate a Coco 3 with a 
floppy drive controller containing an HDB-DOS ROM with Becker Port support 
instead of the DECB ROM. I modified his patch to add another target, 
'coco2dw1' to emulate a Coco 2 instead. You will need the new ROMS, 
'coco3dw1.zip' and 'coco2dw1.zip', to use the new targets. You can get the 
ROMS here:

Enjoy!
