Title: Change shebang line

Using /usr/bin/env allows this script to call Python irregardless of
where Python is installed itself, hence not hard-coding the path in
the program.

On some systems, Python 3 is the default Python interpreter and hence
using plain 'python' in the shebang line would cause an error. It is
recommended in PEP 394 [1] to use 'python2' in shebang lines if the
program is to be run with Python 2.
