Title: Updated user guide ch.17: Plugging in custom UserEntityManager / GroupEntityManager

Added a section to User Guide on how to override SessionFactory and plugin new classes for custom identity management solution.

Reason is this forum post http://forums.activiti.org/content/identity-service-process-engine-only-no-explorer and the fact that this is a common use case IMHO that deserves mentioning in the docs.
