notBD 0.11 - scrolling screen demo with large map

["Andrew Davie" <atari2600@xxxxxxxxxxxxx>]

Here's the next version of my game engine.
I found/fixed the screen shake, put in some test graphics.
In an hour or so from when I write, the MPG of this in action will finish 
uploading, and be at www.atari2600.org/awesome.mpg
Cheers
A
