Forum OpenACS Development: Allow user entered email, new feature, acs-authentication/acs-kernel

In some cases when you are using an external authentication authority, the email field maybe not be filled in.

To deal with this I propose adding an optional setting per authenticaiton authority that will allow users to enter their email if it was not provided by the authority. This will deafult to false, not changing the exisitng behavior.

Any objections or suggestions?
