this patch adds the possibility to have a static (as in non-scrolling) background

in the launcher. major drawback: most of our machines (at least the SA1100
based ones) are too slow to make it flicker free w/ tracking (repainting while
dragging the scrollbar). so i needed to disable tracking for the static background.
it's a hidden setting and disabled per default. please play around with it and
give me your comments. How to enable:
Launcher.conf:
[GUI]
StaticBackground = 1
