Cobertura XML output format doesn't exactly match real cobertura format for class names, method names

[RichardBradley]

See [https://github.com//pull/133#discussion_r46520752]
and [https://github.com//issues/27#issuecomment-161542359]

The class name and method name are wrong in the scoverage output in "cobertura" XML output mode, when compared to a real Cobertura coverage run.
