Fix for use of the strpos-function which would lead to the realm being appended to the principal when it already was. This would lead to the principal not being correctly checked against kerberos authentication.
Major updates to bring functionality inline with the 7.x-2.x branch. Also added ability to pick default role for accounts created by kerberos_authentication.
Major simplifications to code, removed need for module specific schema for settings.
Code formatted and modified to comply with Drupal code guidelines.
Simplified admin interface.
Now restricted to a single Kerberos Realm, instead of multiple realms.
