Feature Request: Show More/Fewer Asteroids

[alphap1us]

I would like to request an option to toggle the number of asteroids that Celestia displays, similar to the "Show More Stars/Show Fewer Stars" option. This way, people don't have to screw around in the directory structure when they want to have a good frame rate or look at a lot of asteroids in detail. A side benefit would be that all the asteroid scc's floating around could be made into one big scc to avoid confusion. My guess is that this would be easy, since the code could be reused from the stars option. Is this true?
