Create a 'pokemonsay' python script

The python script is there to act as a 'cowsay' version but for
pokemon. It uses 'cowsay' internally, calling a subprocess to
handle cowsay.

The script doesn't accept many arguments (actually none), that's
something that can be improved. But it does display a nice result.
