• Add logos to the repo
• Add SVG versions of the logos
• Remove external link to Google Drive
• Rename logo files to be more coherent
• Reorganize directory structure of logos. Now all logos are under assets/images/logos and are divided into icons, png, and svg.
• Use svg for embedded images in the logos page where it makes sense (i.e. where they are smaller than their png counterpart)

NOTE: when this is merged we need to manually remove the img/logos folder from eos. There are a couple of images in there that don't seem to belong anywhere (final-splash-mask-*.gif) - not sure if we want to keep them...

This is super nice! Maybe not for this PR, but it could potentially also be nice to have a button/link that allows users to download an archive with all logos.

I will let @dpiparo and/or @couet comment on the note you made.
