Add metadata for TheGamesDB to games database

[intvsteve]

It may be extremely helpful to add support for "standard" ROM file names so scraping tools that operate on file names can be used, e.g. The Games DB.net. Need to see how that would work for Intellivision.

Would be nice to just create a custom Intellivision scraper. Each entry contains the following fields: Name - string Description - string Image - string (path) Video - string (path) - formats? Marquee string (path) - supported file formats? Thumbnail - string (path) (not used?) Rating - double - 0-1 Release Date - date time format, e.g. %Y%m%dT%H%M%S%F%q - YYYYMMDDTHHMMSS - time ignored Developer - string Publisher - string Genre - string Players - integer Favorite - bool - update favorites? Hidden - bool - hide from list? Kidgame - bool - true if kid-friendly?

For a folder: name desc image thumbnail (not used?)
