Enhancement request: Fixing horizon during manual-mode time travel

[GoogleCodeExporter]

(This is my first post to code.google - please let me know if there is a better 
place to talk about these)

During time-travel in manual-mode, it is useful to fix the horizon and let the 
stars (and others) move in the background. This gives me an idea of what to 
expect(over time)in a certain section of the sky from where I am currently 
stationed.

I have made a very small change - locally - to AstronomerModelImpl for this 
feature and is working neatly. Also added a toggle for this feature in the 
menus.

P.S: I have a few other such code changes and enhancement requests - but I am 
not sure what the exact process is for getting these changes reviewed and 
submitting them. Could the project owners or someone else provide some 
direction?

Thanks!
