Merge branch 'federated_profile' into 'master'

Add preauth mapper for UW System authenticated user. Bump to version 1.3.0

Creates an alternative  to the default Preauth attributes mapper (which is UW-Madison focused) that is specific to the common attributes for an authenticated UW System user.  

Note that in the System context eppn replaces uid as the response for usernameHeader, because uid is no longer a meaningful identifier in a federated context where the bare uid might not be unique unless it's scoped to an individual campus. 

The more the merrier: @paul.erickson @ahoffmann
