Installation Fixes and Improvements

Installation as well as distribution generation are now simplified.
With the elimination of MinGW support there is now a unique set of
platform binaries for 32-bit and 64-bit Windows. Pip will now
automatically choose the proper binary wheel or the source
distribution, depending under which platform and Python version it
is being invoked.

	* README.md: add installation section
	* setup.py: rewrite to use bdist_wheel for Windows
