install_requires a bit ugly

[Martijn Faassen]

I see this in the generated setup.py:

    install_requires=[
        'morepath','more.chameleon'
    ],

which isn't super-pretty. Is it possible to add some whitespace so they're both on separate lines?

I thought I'd get away with that. Jinja2's whitespace handling is not the greatest ;)
