[Fix Bug 933907] fix order of logout.html js files

The issue here was that logout_view.js must come after the browserid_js files. However, we can't compress "browserid_js()" nor can we compress an external file(include.js). It is possible to use the {% compress_js %} tags twice, but, this seems line a cleaner solution. According to the django_browserid docs, you can just output these two files manually instead of using browserid_js() if you want, so that's what I've done in this particular file.
