[development] user account email required?

[Chris Johnson]

When an admin edits a user's account, say to add a role, and then tries to 
save the result, the form requires that an email address be entered.  Yet the 
database itself does NOT require email addresses.  If one is using something 
like LDAP or other alternative authentication methods, the email field is 
often blank.  So now the admin is out of luck because she can't update the 
record, as she doesn't know the email address.

I believe this should be changed to remove the requirement for an email 
address to be present.

Is there some reason why it needs to be this way, or to not create such a patch?
