KBUS surgery in progress

If you've browsed the kbus source on googlecode recently, you may have noticed that it has grown a few more repositories - kernel, cppkbus, jkbus and web. These are in flux at the moment; the eventual goal is to split them and their history out of the 'default' repository. In the meantime, we're going to leave the default repository untouched until we're ready to throw the Big Switch - do not adjust your set!

Mercurial's subrepository support is rather neat. At the moment the plan is to have the kbus 'default' repository check out everything you need to use it (kernel module, libkbus, tools, jkbus and cppkbus) along with the docs source; the built HTML docs, talks and slides will be hived off to their own repository so you don't have to download them if you don't want to.
