scripts: Add script to init bee file for pypi package

This script can be used to create a bee file for a python
package available from pypi.

Howto:

 * search for the package at https://pypi.python.org/pypi to get the
   latest version
 * call the script with the package name and the version number.

   e.g. : scripts/init-pythonpackage PrettyTable 0.7.2

   note: case is not relevant in the package name

   this will create a new bee file python-PKG-VER-0.be0

 * execute the bee file generated from the previous step

   e.g. : ./python-prettytable-0.7.2-0.be0

scripts/init-pythonpackage
