Added Organization View for GHOP.
Along with adding the View, the View is also registered with sitemap
in the GHOP module's callback.py
from django.contrib import admin
from django.contrib.sites.models import Site
class SiteAdmin(admin.ModelAdmin):
list_display = ('domain', 'name')
search_fields = ('domain', 'name')
admin.site.register(Site, SiteAdmin)
