v3.0

• Feature: Script and configuration are now separate. This allows for
  script updating without having to re-input configuration settings.
• Feature: New option to enable/disable keeping subtitles. (addressed
  issue #13)
• Feature: New option to allow for a separate output path. (feature
  request from reddit).
• Behavior: Script now explicitly deletes MKVs when an identical MP4 (same
  filename) already exists. This cuts down on script run-time when
  duplicate files exist.
• Behavior: When run manually, script gives live update of how many files have been
  found. This serves to let the user know the script is functioning
  properly when run against large libraries, where file discovery can take
  a while.
