configuration updates to support automatic deployment using Fabric
turn on forward_agent
fixed import
added djsupervisor to the installed apps
Merge branch 'develop' into feature/deployment_automation

* develop:
  there were duplicate test names, when that happens the second method overrides the first, in this case the second test was redundant so it was removed.
  added check for isites_tool_link, the link to the isite should only be shown when there is not isites_tool_link and when there is a topic id.
  Added new unit test for new helper methods
  fixed the version number of django-auth-lti
  removed unused imports, fixed some tests, refactored mocks

Merge branch 'develop' into feature/deployment_automation

* develop:
  Updated our Django requirement to be < version 1.7
  incorporated changes from code review
  Update text in header
  added error page in lecture video tool for the case of no course isite.
  slightly simpler fix
  hotfix for broken reserves tool: code wasn't handling the case where a course is associated with an iSite but that site doesn't have a reserves tool on it.  In any case, we don't even need to try to find that topic now that we're using a standalone topic, so if a standalone topic is configured we will bypass this lookup altogether.
  split new test file off tests.py modified existing tests to use new utils for get section, check for resource link match, validate course match added new tests for resource link and course validation mismatches

  Collapse setting of enrollment_count in edit_section view to one line.  Add final tests for edit_section in separate file.
  Update template rendering that happens when section could not be updated during edit_section.  Add some more edit_section tests.
  Initial foray into splitting out edit_section tests.  Modified edit_section url to include section_id in url, minor style and PEP-8 cleanup in view method.
created a new generic gunicorn config; added demo config
added separate deploy requirements file; moved fabric library there.
Use dj_static to serve static files -- this will simplify upstream webserver configuration.  Moved the STATIC_ROOT setting to base since it's the same everywhere.
