[Distutils] Microsoft Visual C++ Compiler for Python 2.7

[Olivier Grisel]

Thank you very Steve for pushing that installer out, this is very appreciated.

What is the story for project maintainers who want to also support
Python 3.3+ (for 32 bit and 64 bit python) for their project with
binary wheels for windows? At the moment it's possible to use the
Windows SDK as documented here:

  http://scikit-learn.org/dev/install.html#building-on-windows

However getting VC Express + Windows SDK is hard and slow to setup and
cannot be scripted in a CI environment.

In the mean time, it's possible to use CI environments that already
feature all the necessary versions of the VC compilers and libraries
such as appveyor.com, see this demo project:
