Multiple updates:

    * Removed support for hourly runs, as it's not really all that
      useful
    * Added support for passing extra options to fstrim, and added
      default extra option to only discard blocks of 64k or more free
      space.
    * Modified structure to be more anacron friendly
    * Fixed minor error in metadata.xml
