use VGA Terminal and PS2Keyboard from FabGL

[ghost]

Hello with FabGL and ueforth, we can easily get a standalone forth computer!

Any plan to integrate FabGL into ueforth? In a basic form a 2 color text Terminal running on VGA2Controller can be used, and advanced support for drawing add audio could be added for gaming programming.

Thanks!

I figured out that change the default I/O to a VGA Terminal is simple:

It looks like this :)
