Support for custom User and Group management

[jfendler]

Hi,

nice job of providing Activiti integration for Ninja. Thanks.

Is there any chance of providing support for custom UserManager/GroupManager implementations?
E.g. as done here: http://developer4life.blogspot.com/2012/02/activiti-authentication-and-identity.html

It's not really critical, but would be a very nice feature (not the implementation itself, but allowing for configuration extensions to implement and bind such managers before the ProcessEngine is built from in the module.
