Bython

- Bython is now a Python package! That means you can install it with setuptools, instead of the clunky Makefile used earlier. It is now also available on PyPI, so you should be able to install it via `pip`.
- Support for importing bython modules in python via a new `bython_import` function.
- Improvements in the Bython code generated by `py2by`, specifically the placement of closing braces
- Several smaller improvements and bugfixes.

After several bugfixes version 0.6 is released. This version doesn't contain that much new features, but fixes some important bugs.

- Handling of empty {}. Now, 'pass' is autmatically inserted in empty braces.
- The resulting Python code is more in line with the styling guidelines
- More robust and detailed error printing
- A verbose flag ('-v', version is now '-V' instead) to let you see what's going on

New version of Bython, some new features include:

- Automatic parsing of imported files
- A translator from python to bython has been added
- Bython will no longer mess with your working directory, but place temporary files in a dedicated dot-folder in home instead
- Several smaller bugfixes and improvements
