Please add Screenscraper support

Please add Screenscraper support (https://www.screenscraper.fr/); the website is in French but Google Chrome should translate it on the fly.

Screenscraper hosts video clips, similar to EmuMovies. I became aware of it through using Batocera Linux. Batocera gets you to enter Screenscraper login credentials the same way that Launchbox gets you to enter EmuMovie login credentials and the downloads videoclips, the major difference is that Screenscraper is free.

Screen scraper is free software popularly supported by Emulation Station. It is reasonable to support launchbox as well.
