Fix copying of binary files in nested paths

This solves a problem where files in nested, templated paths would raise an IOError:
e.g. {{cookiecutter.repo_name}}/{{cookiecutter.repo_name}}/binaryfile

This also removes the requirements file from tox.ini (since it doesn't exist). Instead, deps are
specified explicitly.

Force fwd slashes for Jinja's env.get_template() (#37)

env.get_template() on Windows. This is a workaround to fix that.
