Embedding Thumbnails with Cura

[mattheys]

Hi,

This isn't correct, Cura2Moonraker isn't required as you can use Post Processing Scripts out of the box.

docs/features/thumbnails.md

Line 50 in 6a8e373

## Cura

You create thumbnails and embed them in the GCode with Post Processing Scripts, I added the Create Thumbnail script twice, once with 32x32 and another with 400x300 and it works with the thumbnails visible in Mainsail.

This is handy because I can remotly slice something and send it to Mainsail over the internet which I can't do with the plugin mentioned because I use Authelia for Reverse Proxy/Forward Auth protection and it gets in the way.
