refactor install process:

* user is dropped into a shell, where the user can run tools like fdisk to partition a disk
* user needs to add a file called "disklayout" where it specifies SWAP, INSTALLDEVICE and TARGETDRIVE
* depending on the values of these the installscript might need to be fixed to get the GRUB configuration right

It's still somewhat inflexible, but it gives the user a bit more control than the old scheme
