Switch setup.py to setuptools, enable nosetests and sphinx
Explicitly mention template directories in setup.py and make Templater use PackageLoader instead of FileSystemLoader (this should then also work for brian2 installed as a zip file)
include docs_sphinx directory in source distributions (allowing to build documentation)

Merge remote-tracking branch 'origin/master' into devices2
