Add SVGs by Souly

[SoulyVEVO]

A bunch of SVGs for different skins

I also added the background snowflake for freezelaser, if anyone wants to recreate the entire extras image as SVG in the future then they can use that.

hmm seems like the teeworlds font doesnt show up in preview, is there any way to fix that? can i somehow embed the font into the file itself?

The idea for this repository is to rebuild svgs for the images that only exist as png in the ddnet repo so users can play the standard ddnet client with higher resolutions.

The svg files in this repo should directly map to a file in here https://github.com/ddnet/ddnet/tree/a09c608d4241126fd2e1c11b805af0f8fe047971/data

The freeze laser can be useful yes but it should be pushed as the full https://github.com/ddnet/ddnet/blob/a09c608d4241126fd2e1c11b805af0f8fe047971/data/extras.png

Your skins are cute and I hope they are persisted somewhere publicly available. A collection of community skins as svgs would be nice, not sure if it exists.
