Updated settings for devstack django debug toolbar

[wedaly]

#2177 Updated the Django debug toolbar and dev settings, but not devstack settings. This caused rake devstack to raise an exception:

django.core.exceptions.ImproperlyConfigured: Error importing debug panel debug_toolbar.panels.settings_vars: "No module named settings_vars"

This PR resolves the issue by updating devstack settings to match dev settings.

The test failures are a casualty of some git juggling last night for the release. Will merge once I get a clean build.

#2171 only updated [cms,lms]/envs/dev.py - and even there it left a problem - a commented out ProfilingDebugPanel (the new debug toolbar panel name is now ProfilingPanel - see http://django-debug-toolbar.readthedocs.org/en/1.0/panels.html;

This - #2208 - caught a few more files - [cms,lms]/envs/devstack.py - but also left the problem lurking in the comments by not updating the ProfilingPanel name (so that still needs to happen).

The files you still missed are:

• lms/envs/content.py
• cms/envs/dev_dbperf.py
• lms/envs/devplus.py

You can find my patch file from the head as of last night here: https://gist.github.com/yarko/8473409

@yarko Thanks for pointing that out. I have an immediate need to get devstack fixed, so I'm going to merge this as-is. Could you please open a separate PR for the changes in your patch?

@yarko I can't run Studio now locally (it works on the devstack), and I think it is related to the django debug toolbar change. Are you aware of the problem? Do you have a proposed change yet?
