Work on test fixtures: - get rid both on bo and front of 2 fixtures files for documents - correct dl_fixtures to reflect this - upgrade mirage from 0.1.13 to 0.2.0 - download new version of documents fixtures including geo information

As we're using the rspec fixtures structure, we can run them quite simply

    rake spec_prep
    puppet apply --modulepath spec/fixtures/modules -e 'include demo1'
