Bookmarklet for Generating Plex Supported Filename for Movies from TMDB or IMDB

generate-plex-movie-filename.js

/* 
    The following code is used to generate a string that adheres to a Plex filename
    convention for movie titles. This code can strip page titles from either 
    TMDB or IMDB and put them in dot notation of:

    Movie.Title.Year.{source-sourceId}

    An extension is not provided as I do not know the extension of the target file.
