Does the new Plex Movie Scanner have backward compatiblity with old IMDB id format?

@Volts @ChuckPa

I’m think the old scanner used it, and I thought I remember seeing it in some official Plex documentation but maybe not. There was a top Reddit post recommending doing this and this thread: Plex server to look for a .plexmatch file when matching a show/movie

So another question:

What if I were to include the TMDB # in addition to the IMDB?

Would that lead to better matching (ie. fallback for when a title doesn’t exist on IMDB)?
