WS SCIM 2 to implement PATCH method

The PATH http method is essential for membership updates via the group object. Without it, you can't add or delete individual members from a membership list, rather you need to pass back the whole membership list with just one entry changed.

This was not working in the Penn State Scim implementation, the error was

java.lang.UnsupportedOperationException: PATCH operations are not implemented at this time.
