a hell lot of cleanup/rewrite:
* diskdrake_interactive created, diskdrake is now interactive aware * added some documentation about the structure used for partitioning * all_hds now contain the various hds, lvm, raid * cleanup the isLVM, isRAID and alike functions * field {type} in detect_devices is now {media_type} * detect_devices::floppies is now floppies_dev * removed old function prototypes
