KML files always show 0MB

[Fergui]

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.
