Did some css clean up as well. Removed the action_required_img class,
which is just a duplicate of the loading_gif.

Verify Help button redirects to the right URL

When choosing "Help", in the top bar user drop-down menu,
the browser should redirect to http://docs.openstack.org/
Different distributions might customize the redirection URL,
but the above should be the default.

I added test_dashboard_help_redirection.py, go_to_help_page
method in basepage and the help_url value to horizon.conf
(also forced a change in config.py)
