The integration of the CBAC methods into the ApplicationController is currently risky, since there is a pretty big chance
of name clashes. For example, the AuthenticatedSystem plugin also has a method called "current_user", which
returns a complete User model instead of an integer for the user's id.

Cleaner integration could be accomplished by clearly setting the methods apart from other methods by prefixing them
with "cbac", such as "cbac_current_user" instead of "current_user".

current_user has been renamed to current_user_id to allow for
integration between AuthenticatedSystem and CBAC. (Also, the
method name is better, since it returns an id and not a User
object or some such).
