linhes-system: include add_storage.py.
This program is used to detect and autoadd storage to mythtv storage groups. Currently it's not hooked up to anything, but hopefully in the near future it will be an automated process. add_storage will only prompt for new disks, it will skip the following: - optical disks - disks that are in fstab - disks that are mounted (but may not be in fstab) - disks smaller then 5mb refs #796
