[Distutils] Installing non-program files into the lib directory

yeah, i have figured this out. i have the exact same setup, a couple
resources that need to be in the same directory as the .PY files that
use them.

i have a "lib" directory with all the files i want in my final 
directory. here's the relevant snips from my setup.py file to get
them all installed nicely

note that it took me quite awhile to get everything to this stage,
but now it is working beautifully.

you'll see the main secret is creating my own "install_data"
command that actually puts files where the installation is
going, instead of pretty much random locations on different
platforms.

hope this helps!
