Include the dwelling fractions app into the OQP package

[Ben Wyss]

In the previous spint we investigated the integration of leaflet/mbtiles into the OQP (geonode 1.2) and we were able to integrate the app and it's dependancies.
This bug is to integrate this application into the installation script of the platform and commit to Git.

In order to add the dwelling fractions & exposure export application to the OQP I applied the following setting by hand to an existing OQP installation:

HTML and JS:

add exposure_export.html into
/etc/geonode/templates.apps/oq-platform2

exposure_export.html is then referenced into the
/var/lib/openquake/oq-ui-api/etc/geonode/templates/oq-platform/includes/menu.html
&
/etc/geonode/templates/oq-platform/includes/menu.html
<li><a href="/oq-platform2/exposure_export.html">Exposure Country Aggregate Data</a></li>

then add the binding in django to the new exposure_export.html page in: /var/lib/geonode/src/GeoNodePy/geonode/urls.py

place the leaflet-legend.css into ~/Projects/test/oq-platform/oq-ui-api/etc/geonode/static/theme/
&
/etc/geonode/static/theme
&
/var/lib/openquake/oq-ui-api/etc/geonode/static/theme/
&
/var/www/geonode/static/theme/

add external libs with git submodule
place external libraries (Leaflet, Leaflet.Draw, Wax, L.Wax, Jquery) into: ~/Projects/test/oq-platform/oq-ui-client2/src & /var/www/geonode/static/oq-platform2/src/

Django:

new 'exposure' django project is added into: ~/Projects/test/oq-platform/oq-ui-api/geonode

new project is added into settings.py

an external database connection is made by adding to local_settings.py:

'geddb': {
            'ENGINE': 'django.db.backends.postgresql_psycopg2',
            'NAME': 'ged',
            'USER': '<name>',
            'PASSWORD': '<passu>',
            'HOST': '<IP>',
            'PORT': <port>,
            'OPTIONS': {
                'sslmode': 'require',
      }
    }

and

DATABASE_ROUTERS = ['exposure.router.GedRouter']

the new project is referenced into the django root url.py with:

(r'^exposure/', include('geonode.exposure.urls')),

and

    url(r'^oq-platform2/exposure_export.html$', 'django.views.generic.simple.direct_to_template',
    {'template': 'oq-platform2/exposure_export.html'}, name='exposure_country'),
