Subject: The initial commit of refactoring the user/group adminsitration into
 a driver. Create an Identity library that defines the interface the Gallery3
 expects Move the user and group helpers into the gallery module to provide
 the familiar interface into the Identity library. Create a Gallery Identity
 back-end that is supplied by the user module.

The vision here is that all user and group code that is gallery or ui specific
is contained within the core product.  Anything that relates to manipulating a
user or group is contained in the back end code that can be replaced.
