Ask registering users for email address, too

[ImreOlajos]

It'd be nice if the self-registration asked users for the email address, too. This would be one of my proposed enhancements to make WUHU work for a fully online party, too.

Optionally, verification of user identity would work with this email, too, i.e. don't activate the user in the system until the user confirmed their email address by clicking a link in their email.

Outside of scope, but you're welcome to write a plugin.
