Teak setup.py

* Pass markdown directly to `long_description` and specify
  `long_description_content_type`.  Don't use pandoc.
* Load version from `julia/release.py`.  This number can be accessed via
  `julia.__version__` at runtime now.
* Bump version number to 0.2.0.dev.
* Pass `zip_safe=False`.
