Refactoring

I've started to refactoring the code a bit, doing cleanups and moving code around. This will result in a flatter source tree. I'll probably also get rid of the include directory, moving its contents down to the root.

I'm slowly working my way to a 0.0 release. Things left to do is;

* implement an ext2 file system driver,
* add a 'variable driver' that stores variables on disk, and
* write a simple boot manager

The boot manager should be responsible for booting GRUB2 from disk. When that is done, my next focus is to get the whole thing running on LinuxBIOS.
