*DO NOT MERGE*  Removing WebTrends from front-end use

Removes WebTrends from the site front-end.  There are a few WEBTRENDS settings still in the settings.py file, however, because many of the dashboard models use them.  We should  discuss whether or not gutting anything with WebTrends settings will cause the world to explode.

I have this marked as "DO NOT MERGE" because we should do one last confirmation with Teoli / OpenJCK before doing final merge.
