500 error page does not have correct link to Home

[Chris Buccella]

The page for a HTTP 500 error ("Something went wrong!") has a link for Home. The link is simply "/", which may not be the application root as set in local_settings.py. The link should reflect this setting.

    Use WEBROOT setting for the 500 page home button

    The home button on the 500 page currently links to "/" which is not
    always the true app root, in settings we define a WEBROOT
    variable so that we can inform the app of its actual location.

    This patch uses that variable to set href location for the home link
    on the 500 page, so it will be acurate for all cases.

    To make this possible the load_conf template tag now returns conf
    itself instead of conf.HORIZON_CONFIG giving the template access to
    more of the settings including WEBROOT.
