Okay, I have uploaded a few candidates. Unfortunately, due to the necessary downsizing, you loose a lot of the clearness of the image either way. If you like on of them, you can try just renaming it to "File:Favicon.ico". If that doesn't work, try downloading and re-uploading it.

- Edit:

When renaming, just change the name to "Favicon.ico". There is another dropdown that should automatically put it in the correct namespace.
