Initial implementation of doing NSI v2 authorization based on the SOAP headers (instead of http header)
Retrieve oAuth token on Spring security side using a (naive) XPath expression
Better xpath matching
adopt newer properties
Modify tests and xpath query to accomodate xml format as agreed with Nordunet
Throwing an IAE is more appropriate than just a RuntimeException
exclude retrieving the wsdl from going through the security-filter chain (always allow access)
Merge branch 'nsi2-msg-based-authz'
