Added a sample IDatasetForm to show how we can implement a custom form from a plugin.

Currently the form is pretty ugly and the controller_plugin needs simplifying so that it makes a more sensible example. The setup.py has had the plugins section changed and the version upgraded to 0.2 ready for when it is complete
