Clean up requirements.txt

[jhamrick]

It should only include direct dependencies, not psiturk dependencies -- it should just have a psiturk version, and then the psiturk dependencies will be installed automatically.

Hm, actually, this didn't work because the dependencies of the dependencies are not getting automatically installed with pip.

Reverted in e174481ddd13ea8868b66972f8d760b34fa82df9 until this is figured out.

I just figured out how to do this, I think, from some other stuff I was working on...

Basically, in setup.py, we can read in the requirements.txt file and add stuff to the install_requires. Something like this:

from distutils.core import setup

setup_args = dict(... existing setup stuff ...)

if 'setuptools' in sys.modules:
    setup_args['install_requires'] = install_requires = []
    with open('requirements.txt') as f:
        for line in f.readlines():
            req = line.strip()
            if not req or req.startswith(('-e', '#')):
                continue
            install_requires.append(req)

setup(**setup_args)

I am not 100% sure if this will work because it's not exactly the same issue, but is probably worth trying.
