[Radiant] Extending SiteController -- how to get current_user

[Sean Cribbs]

The current_user method used in Radiant and the member system are 
probably (or should be) different things, unless all of your members 
should have logins to the admin interface.  However, assuming this is 
not the case,  you'll need to extend the SiteController, probably using 
an included module.  The module would redefine/intercept various methods 
in the controller.  When we built something similar for Redken, we 
turned on the session (using session :disabled => false),  used 
alias_method_chain to intercept process_page so we could pass the 
current_user to the page, and added some before_filters to login from 
cookies and do other similar tasks.  All told, it was probably around 30 
lines of code, outside of the generated user/login boilerplate.
