add install requirements to setup.py
Make the spec in pip_install compatible with pip specifications.

Currently, commands like `conda install cherrypy==3.2.2` or `conda install cherrypy=3.2.2` do not work because the spec computed using arg2spec() does not contain any equal signs but if conda decides to use pip as a failback installer, the spec needs to add back the equal signs since pip needs them.
in order to make conda pip installable, we need to use setuptools (for install_requires)
start work on conda init command
add creation of conda-meta for Python
