Installation breaks with new setuptools

[joostrijneveld]

This is the same issue as rcssmin is suffering from, documented at https://github.com/ndparker/rcssmin/issues/6

People that are after a quick solution, you can downgrade setuptools using pip with these 2 commands:

• pip uninstall setuptools
• pip install -I setuptools==28.6.1

Then the pip install should work on whatever need rjsmin, in my case it was django-compressor.

This has been resolved in setuptools 28.7.1.
