Updated linux-unlimited to work with Python 2.7 and 3.x....

Didn't test it with 2.6. Also cleaned up code a bit to be more inline with PEP 8. Its not perfect, but a step in the right direction. Similar modifications to the windows version should work, but I don't have a box to test that at the moment, so I am going to leave it. I didn't touch the readme, but it should be updated.

Saw your talk today and enjoyed it. I'll say hello if I see you tomorrow.
