remove djangologging

djangologging module was abandoned in 2009, and made largely
unnecessary by Django 1.3+. Author recommended switching to
debut-toolbar which is already integrated into this branch

readme changes
update rooibos.contrib.compressor

See http://django-compressor.readthedocs.org/en/latest/quickstart/ for
all fun that's been added by deleting the old version- one big thing is
that the setting in settings_local is now COMPRESS_ENABLED not COMPRESS
to toggle compression.
