Remove redundant attribute [Was: class and className entries]

[dgwyer]

While inspecting some of the rendered SVG code I noticed that some group elements contain a mixture of class and className attributes. The className attribute appears to mirror the class attribute.

See this screenshot for an example:

In the rendered markup should we be outputting a class attribute only?

It should, good catch! At the very least class itself is still present which means there is no functional bug, but redundant attribute definitely worth removing.
