Workflow fix 1

Two changes:
 - Changed dtgov-war to depend on dtgov-workflows as "test" scope (to keep it from being included in the .war itself). I think this was the intent, but correct me if I am misunderstanding something please! :)

 - Modified the SimpleReleaseProcess workflow to workaround the type issue that I am seeing. I believe that this may be a bug in JBPM6, as I cannot find a reason for Response to be type "Object" in this workflow.
