Hot fix for #1253 to autorun KA Lite server on OSX if set.

Hi @aronasorman

Hot fix for #1253 - where I accidentally "cleaned-up" the code to automatically run the start.sh script which runs the KA Lite server upon login on OSX.
Hot fix to pass Travis tests by checking that `lang_name` has a value for dubbed video data on `get_dubbed_video_map()`.
This overrides the previous commits to cherry-pick final codes to remove the debug commits.
