Test for user index and editing.

These tests are rudimentary tests to see if a user listing can be done
and whether a user can be edited after already in the system.  There
are loads of security flaws that could exist in an implementation that
are not addressed with these tests.  Those will come later after we
can be certain that users can log in to the system.
Tests for deleting users.

These simple tests just checks that the list of users includes links
to delete and that when clicked they are removed from the system.
Add tests for password field.

Do not allow password fields to be provided using text fields since
the text is visible on screen.
