Rollback Django Debug Toolbar from 1.0.1 to 0.9.4

Due to issues with require.js and the latest version of the toolbar.
Also included a note in the requirements file explaining the situation, and what
needs to happen before this can be upgrade properly.

Fix STUD-1316

This bug affected unpublishing content (and would trigger an error
message in studio). The fix was to uncouple the rendering of the studio_view
of an xblock with the student_view, so that content that wasn't in
draft mode already wouldn't be modified by early rendering of the
studio_view.

[STUD-1316]

fixed the webchat Freenode URL

fix partial work done for changes in django-debug-toolbar-1.0.1

LMS: Adds Language Selection Menu

Fixed bok-choy acceptance tests

* Don't show sidebar if only one language is present
* only add in the default language code if it's not already present

instead of the current language.

Also, refactor tests such that we're not deleting users or prefs

Will pass once the language persistence stuff gets merged in

make openendedchild and open_ended_module_v1 act enough like xblocks to get xblock 18n

Ahodges documentation lms

Update change log three new lines look correct cautiously merging even though some tests failed
