Fix Python-based commands/scripts for Python 2.7 on Windows 7 (x64)

Due to Windows 7 UAC requirements Python-based commands (such as easy_install,
ipython, nosetests, pip...) open a new terminal window, making it hard to read
the output.

As documented elsewhere [1]_, the most practical solution is apparently replacing
the executables with a batch file that calls the Python script. This is tedious to
do by hand if you have many packages that install new commands.

This script automates the process: it moves the executables (e.g., pip.exe) and
their manifest files (e.g., pip.exe.manifest) to a separate directory, and replaces
them with a batch file with the same name (e.g., pip.bat). It should be run without
arguments::
