Well, you cannot expect every app to have such preferences, this device
runs generic linux apps that aren't made specially for the freerunner. 
Now, of course the app loader can do this, similiar to how we already 
request the cpu/backlight when launching some apps.

But there is a problem. The user may switch between several apps with
different rotation needs. (xmahjongg needs landscape, tetris needs 
portrait, ...)  How will omnewrotate be notified about this?
