Taverna 2

WSDL Activity has been modified to work with Security Agents that are called to modify the SOAP message to add security headers. At the moment, only username and password based authentication has been implemented (signatures and encryption still remain). However, there is a problem with raven loading of axis libraries that needs to be sorted before proceeding.

Remaining thing to be done is to set up Firefox-style fetching of services' certificates for https connections and automatic saving to Credential Manager.
