Cleanup svgs of new logo

[jpfeuffer]

The SVG of the new logo is very complicated and not well documented for such a simple path.

The SVG classes should have descriptive names and ideally the paths would be a single path per character such that you can adjust colors/strokes/fills on your own.

@poshul do we have contact to the original creator? maybe we could ask them? Should be a simple merge or deletion of some overlapping paths. Plus some find replace in the xml
