The ``groups`` and ``roles`` nodes may be removed from original schema
Made a general pass through display strings and messages, editing for consistency. Several prominent text items were changed, but the result is simpler, and fits with a more consistent use of subject and complete verb. Use of the word successfully was removed in several items, because it is not needed. A few items were reworded. Affected strings used in tests were updated.
The improved wording for the register line is still too jambed up against the login button, so added a ul with class nav nav-list, and with a divider to separate the login and register buttons on separate lines.
Missed replacing a use of Sign Up! with Register.
Fixed a line that assumes that the registration was automatic, by making it more generic, to also for self-registration.
Fixed the test text problem j23d found.
