Setup: make pip installable

This patch makes setuptools a dependency. This is needed to make `setup.py` automatically make the `Opcodes` module available at setup time. Opcodes is made into a setup-time dependency, and if the module is installed with `python setup.py build` or `python setup.py develop` or `pip install PeachPy` or `pip install --editable PeachPy`, then the `python setup.py generate` command is run automatically. This patch depends on Maratyszcza/Opcodes#5 because of the way setuptools handles setup-time dependencies. They are not installed proper, but made available as an .egg file. Opcodes, before Maratyszcza/Opcodes#5, tries to read the XML descriptions by opening a file relative to `__file__`, which is not a thing which can be read with `open()`. Instead, it has to use `pkg_resources` to do so. With these two PRs merged, it should be possible to `pip install git+https://github.com/Maratyszcza/PeachPy`. We could also then discuss making it easy to package up and upload to PyPi. Try removing pip install -r requirements and generate step from installation Add six and enum34 to install_requires Add six to setup_requires Upgrade to Opcodes==0.3.10 Remove peachpy import from setup.py (and duplicate the version number by writing it literally) Fix setup.py for python2.7 Run tests with --no-path-adjustment Put nosetests configuration in setup.cfg Remove Opcodes from install_requires
