Generating a minimal image

I played around with bootstrap and the module system today, and got Factor to generate a 600kb factor.image. The image does not include the compiler and UI, however it does display a listener, and has all the math and collections words in it. If there is any interest in this, I will clean this facility up and make it easier to use. Personally I don't have much interest in making images small. I think the current size of around 6mb is fine, considering it includes full documentation and developer tools.
