KML files always show 0MB

The problem is that when requests try to access the KML url, it fails because of an authentification error. Solution would be to replace the line 122 in src/make_kmz.py by:

r = requests.get(url, stream=True, auth=('user', 'pass'))

This would require to specify 'user' and 'pass'. Therefore, it would be great to take them from etc/conf.json or include them in ~/.netrc file.
