Django 1.5 compatibility
Update travis to pip install Django < 1.6
Use signed cookies for sessions instead of file

This update is a workaround for tests failing when using the file backed

using tempfile.gettempdir() since SESSION_FILE_PATH is not set.
Require python-django15 on rhel6=< fedora 20=<
Remove bogus changelog lines
Update wsgi file to 1.5 compatible
Move static back to media, makes the update smoother
Move from using static to urls

Template syntax for url changed requiring quoting the parameter. This
works correctly under 1.3 and newer.
python-simplejson is required
