Yarko/debug toolbar 1.0 fixes - completes changes for django-debug-toolbar 1.0.1

#2117 began changes, but left commented ProfilingDebugPanel in old form - this fixes;
#2208 added two files, but left out remaining files - this pull adds them;

Also, this pull corrects / adds trailing ',' at MongoDebugPanel in cms/envs/dev_dbperf.py,
In addition to #2208 & #2117, this also updates the 3 remaining files which needed updating.

Note - earlier today, I'd posted a patch (https://gist.github.com/yarko/8473409) of these files prior to #2208 being merged, and posted that patch on edx-code groups, to help  people stuck there.  Sometime today, #2215 was created, but with errors.  Rather than comment on the errors in #2215, I've created this pull based on my work last night, merged with todays master.
