Use git lfs for pdfs and images?

This might be better and help keep the source repo clean.

We would then need to update the CONTRIBUTING.md

Hi @maxnoe @bixel,
I played around a little bit and added git-lfs for everything in the git-lfs branch. I also updated CONTRIBUTING. I mean the repo is not cleaner, per-se, the files (at least their name) are still there. It is just better to handle.

Before merging that in the master someone should make sure that git-lfs is installed on the server and is working...

Now I also rewrote the whole history and did some testing. A branch went from 170MiB to 4.5MiB (if the large file objects are excluded).

As far as I understand it, it should also be ok for people who forget to set up git-lfs working in this repository. Then the file is just uploaded the usual way and can be migrated later to git-lfs if needed. Downside is, that the history is rewritten so the commit-hash changes.

Testing:

And without git-lfs installed we can get it down to under a second:
