What does this requirement give us?

@mjallday There are something only new version of setuptools support, like extra dependencies. Not sure is that the reason I used the new setuptools here, but if it breaks thing, I can actually remove that and fallback to old setuptools, as long as the older version also support extra dependencies in setup.py.

I'm not 100% how new you mean. Balanced supports extras so if we could make it work with that particular version it would make integration easier.

@mjallday Sometimes I just like new version for no reason, maybe it was just my syndrome acting up. Please drop the new setuptools if older version also works.
