Uses out-dated Xubuntu logo

[Elizabeth K. Joseph]

The Xubuntu logo used to denote Derivative (as seen here: http://spreadubuntu.org/en/material/presentation/xubuntu-presentation for example) is several years old.

Current branding images can be found here as "Icon only" for the small sizes: http://xubuntu.org/marketingresources/

I can also provide specific sizes in whatever format is needed.

Thanks for pointing this out. I've changed the icon.
