Bug fixes to revision r596. User Account field in Developer User Profile view needs to be an email not a login name. Header title of User Profile Developer view, when form validation failes is now showing correct value ("Modify existing ..." instead of "Create new user ...").
Add /site/user/profile Developer view for editing arbitrary User entities.
Update /user/profile edit() view to fix TODO about updating the URL when a
POST of the form changes the link_name of the User. Add a Create New User
link to the base.html sidebar mock-up.
