* Incremented version to 0.2.2 for pypi release.
* Removed all post-install hooks. All initialization and configuration
should be done through the cafe-config cli tool.
* Added setup.cfg with support for universal bdist wheel.
* Updated MANIFEST.in file.
* Updated README.rst to reflect new install procedures.
* Modified cafe-config so that initialization command is now just
"cafe-config init".
* Since the ".opencafe" directory is no longer initialized at install
while access to the source code is guaranteed, the plugins are now
distributed as package_data, and installed as such to site-packages
under the new "plugins" directory within the "cafe" namespace.
* The plugins directory is moved to the cafe package directory as
package_data.
* The plugin cache is no longer created at initialization, and all
code relating to it in the cli.py and managers.py file has been
removed.
* Removed pip-requires file in favor of including the only requirement,
'six', in setup.py. The plan is to refactor so as to remove the
dependency on six eventually.
* Renamed test-requirements.txt to test-requires.
* Added Authors.rst
