Adding support for Church Community Builder login.

Beginning with this change all of the Church Management System
integration logic is moving into implementations of the new
IntegrationDriver interface. The desired IntegrationDriver can be
selected by setting the integrationDriver config to the appropriate
class name.

This commit is only moving login support. Progress reporting will move
in a later commit.
