o Make the framework generally more robust. o Figured out how to nest the menu descriptions - no more grotty initialization of menus. o Fix bug with helpline and helpfile not being reset. o Add stubs for the media selection code. Coming next: Fdisk and disklabel screens using Phk's new libdisk stuff.
