/* CHANGELOG

    1.1.03 (7/17/2016)
        - fixed script

    1.1.02 (6/7/2015)
        - fixed script

    1.1.01 (3/14/2015)
        - fixed bug of it liking all videos when username list was empty

    1.1.0 (3/13/2015)
        - added a new option to allow auto-liking of videos from subscribed channels

    1.0.40 (3/12/2015)
        - adapted to YouTube changing like/dislike buttons' classes

    1.0.39 (1/26/2015)
        - changed the timeout of the script so it waits a real 30 seconds, not X amout of intervals
            should be more accurate, especially on weaker computers whose browsers freeze and the intervals overlap

        - adapted to page change (different class name of author link)

    1.0.37 (9/8/2014)
        - adapted to new YouTube style
        - fixed an issue with channel names with punctuation in them not getting "liked"

    1.0.36 (12/17/2013)
        - added a user-script command for the options

    1.0.35 (12/14/2013)
        - started using YouTube Button Container
        - made code more readable by using JSL and @requires

    1.0.34
        - added compatibility for Opera & Chrome
