Separate “Extract thumbnail and video information” settings.

Hello,

I’m using libraries over WAN and caching thumbnails uses ridiculous amount of bandwidth. It also slows down operation by a lot.
This is also the case for slower hardware such as Raspberry Pi even on LAN.

I’ve disabled “Extract thumbnail and video information” for now, but I would like to keep “extract video information” enabled.

I found discussions regarding this dating back to last decade and XBMC team members even back then stated that it would be preferable to have the 2 settings separate.
