Metacat

Clear the code for the method handleInsertOrUpdate.

Add the code to expand the rights holder if it is a group.

Replaced the JiBXException by MarshallingException.

Use the method getContextURL rather than getSecureContextURL in the getCapacities method.
So if the server doesn't support sll, the getCapacities will return a baseURL with http.

correct two minor differences from 2.6 merge: formatId parameter for MetacatHandler and using AuthUtils for gathering group membership information.

Merge in changes from the 2.6.0 release.

merge from 2.6 branch: use AuthUtils to gather user group subjects

Merge changes from the 2.6.0 branch in MNodeService.allowUpdating() so it honors the localhost MN certificate.
