Upgrade and stabilize setup.py to enable perfect packaging

Changes:
 - `python_requires` refined;
 - remove deprecated `classifiers`
 - add new packages to extra test requirements;
 - update keywords;
 - use package_data to bundle data files into distributions
 - get version info from __init__.py module
 - update summary;
 - load README.md and data from __init__.py using re and io modules;
 - add a few more project URLs and remove deprecated
