Andrew Engelbrecht 6ca5bb4d41 Added CAS user whitelist feature
This feature filters users who may log in via CAS. This is useful when
both CAS and password authentication is enabled and there is a mismatch
between some GNU social account names and CAS user names. This prevents
CAS users from logging in as someone else on GNU social.
