[Xmonad] darcs patch: sketch of config/main inversion. (and 3 more)

Hi all, Here's a somewhat cleaner version of the main/config inversion patch. I recommend applying this sooner, rather than later, if we are going to make this change, as there are many small things that need to be fixed, which can be more easily accomplished collaboratively. This set of patches only does the very crudest hacks. But as we've discussed on IRC, making xmonad available as a library would be a Very Good Thing, and this is the only attempt we've gotten going so far at getting this working.
