Remove unused import causing deprecation warning

Warning in the form:
RemovedInDjango19Warning: "ModelXYZ" doesn't declare an explicit app_label
Apparently this happens because it tries to import models before app
configuration runs

helios/__init__.py

-
 from django.conf import settings
 from django.core.urlresolvers import reverse
-from helios.views import election_shortcut
 
 TEMPLATE_BASE = settings.HELIOS_TEMPLATE_BASE or "helios/templates/base.html"
