Setting WEBROOT does not change static paths

[Adam Young]

setting WEBROOT as per commit 2a772d64800070689478a49b6aa26a5893b2067b only changes the paths for the dynamic pages.

I tried just adding STATIC_URL = WEBROOT + 'static/' in
/opt/stack/horizon/openstack_dashboard/local/local_settings.py But apache remoes the /dashboard/ portion and the result was 404.

In order to make the static pages (such as CSS) appear, I had to add the following to /etc/httpd/conf.d/horizon.conf

    Alias /dashboard/static /opt/stack/horizon/static

    Fixing changing WEBROOT from /

    There were a few items missed with the patch enabling changing
    WEBROOT patch.

    First the XStatic files were being unpacked in the wrong directoy
    because root_url was not being passed in. This caused 404 errors
    when running with a different web root.

    This change allows root_url to be passed in on XStatic handling.

    Second, STATIC_URL and MEDIA_URL were not using WEBROOT.
    These now are built with WEBROOT.

    Third, the fa-font-path variable was hard-coded in _variables.scss
    to use "/" as the web root.

    A webroot variable has been added that can be overridden. Additionally,
    a new theme has also been added to change the web root.
