Upcoming OpenId breaking change

[Jeppe Nejsum Madsen]

Hi,

As part of making OpenId more configurable wrt to attribute exchange,
I've removed the default FetchRequest for the email attribute as this
causes myopenid logins to fail.

Instead, a new beforeAuth function can be set which can add extensions
based on the discovered endpoint

Change can be seen here:

If this causes serious trouble for anybody, please speak up...
