Adding script that handles rip and encode with HandBrake

- Can use either a DVD drive (if ripping and encoding) or MKV file (if
  reencoding) as source (-s SOURCE)

- If source looks like DVD (e.g., /dev/X), require track (-t TRACK)

- If source looks like MKV file, can auto-determine output filename based on
  input filename if no name is specified (-n NAME)

- Can specify output directory, otherwise defaults to $HOME/Videos (-d
  DIRECTORY)

- Options for 480p, 720p, and 1080p encode targets, and appends resolution to
  end of output filename
  * Can't remember source of 480p encode flags
  * 720p/1080p based on AppleTV 2/3, but tweak modulus per Plex/Roku forum
    discussion (need to test this out with movies I know I've had aspect ratio
    issues)
Added date to header
Fixed default directory to reference $HOME
Adding script to batch rip a TV DVD (provide range of sequential tracks to rip
as individual episodes)
