Detect IMDb type: TV show/movie/video game

[buzz]

Some sites only make sense for specific types of entries (e.g. GraphTv is only for TV shows).

Add code that detects the type and add a new optional field to sites that limits it to specific type. Something like this:

graphtvmatsf: [
  'GraphTv',
  'data:image/png;base64,...',
  'https://graph.matsf.cloud/tt{{IMDB_ID}}',
  null,
  null,
  ['tv-show']
],

Edit: For video games we could disable the userscript altogether, I suppose.
