Squashing private settings import errors leads to wasted developer time when developers expect settings to be in place, and they aren't. This change only loads private settings if the private.py file exists. If there is an error during the import of that file, the application will not start.

When running locally, XBlocks which access third-party software no longer
cause server errors.

Because devstack inherits from aws, the HTTPS flag was implicitly set to 'on'.
This meant that XBlocks attempted to use SSL when dealing with third-party
components like LTI.  Since SSL is not enabled on devstack, this caused server
errors whenever these features ran.

The django debug toolbar circumvents other middleware with process_view
functions, so it needs to go at the end of our MIDDLEWARE_CLASSES
setting.

This is compatible with Django > 1.5, and allows us to re-enable the ProfilingDebugPanel
