GET workflow-definitions, GET task-instances and GET workflow-instances all now support the new 'exclude' parameter. This is a comma separated list of types to exclude from the results, for example: "wf:adhocTask,wcmwf:*"
Also fixed the filtering logic used in GET task-instances and GET workflow-instances so that multiple filter parameters now work correctly together.
