Add source file and attribution for Dextrose "logo"

A hint by Frederick Grose on sugar-devel caused me to check the Dextrose
"logo" against the Dextrose Wikipedia page [1] and discover that it exactly
matches a CC-BY-SA 3.0 licensed image [2] displayed on that page. In order
to comply with this license, I add both a README file with attribution and
a verbatim copy of the image in SVG format ("source").

+These are the sources for the Dextrose start-up animation - or at least the
+closest thing to source we managed to recreate from the (binary) RPM package;
+the original sources seem to be lost.
+
+The Dextrose "logo" is based on the image [1] of the Glucose chain structure
+from Wikipedia, created by user Acdx [2] and released under the terms of the
+CC-BY-SA 3.0 [3]. We include a verbatim copy of the source file (SVG format)
+as Glucose_chain_structure.svg.
