Cleanup setup.py

[Seanny123]

Modernizes setup.py so that it's compatible with Windows and is less complex.

Simlar to #81, I was also having trouble installing on Windows 10 with Python 3.6. Specifically, I was getting the error:

PS C:\Users\mr_bo\git\hyperopt-sklearn> pip install -e .
Obtaining file:///C:/Users/mr_bo/git/hyperopt-sklearn
    Complete output from command python setup.py egg_info:

      File "c:\users\mr_bo\git\hyperopt\distribute_setup.py", line 150, in use_setuptools
        raise ImportError
    ImportError

    During handling of the above exception, another exception occurred:

    Traceback (most recent call last):

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\mr_bo\git\hyperopt-sklearn\

However, when I deleted the chunk:

if debug: logging.basicConfig(level=logging.DEBUG)
# distribute import and testing
try:
    import distribute_setup
    distribute_setup.use_setuptools()
    logging.debug("distribute_setup.py imported and used")
except ImportError:
    # fallback to setuptools?
    # distribute_setup.py was not in this directory
    if not (setup_tools_fallback):
        import setuptools
        if not (hasattr(setuptools,'_distribute') and \
                setuptools._distribute):
            raise ImportError("distribute was not found and fallback to setuptools was not allowed")
        else:
            logging.debug("distribute_setup.py not found, defaulted to system distribute")
    else:
        logging.debug("distribute_setup.py not found, defaulting to system setuptools")

from setup.py, I was able to install the package. Consequently, I've created this PR to clean up setup.py.

I decided to copy Nengo's style of setup.py. Nengo has stringent setup requirements and it:

• Doesn't use any of the tools I removed.
• Explicitly throws an error if setuptools can't be found.
  • Doesn't bother with include_package_data, which seems to be something which should be replaced with Manifest.in anyways.

Thanks for the PR! Seems to work fine. The one difference I've noticed from the previous version is that it now installs the package as hyperopt-sklearn instead of hpsklearn. (still uses import hpsklearn in python though). I feel like this makes more sense than the old behaviour, and better to change it now than later. There just might be some issues popping up when a PyPI release comes about.
