Adding fault parameters to Service interfaces operations

Hello,

as a consequence of http://www.obeonetwork.com/group/informationsystem/forum/topics/soa-ecore-model-completion-with-fault discussion ; here's 2 commits adding fault parameters to service operations and the corresponding view and tool within service contract designer view.

I've done some tests with new model and everything works fine on Obeo Designer 6.0.

Regards,
