Update setuptools download

[GoogleCodeExporter]

What steps will reproduce the problem?
1. use "setup.py install" with python 3.x
I'm currently using Windows 7, python 3.3, pydicom 1.0.0a.
The result for me will produce the error "cannot build the egg."

It would seem the setuptools download is very outdated (pointing to distribute, 
a deprecated fork of setuptools). 

To fix:
1) change contents of ez_setup.py to the contents of this: 
https://bootstrap.pypa.io/ez_setup.py
2) change setup.py to: from ez_setup import use_setuptools

This will download a current version of setuptools if the user doesn't have it.

Also, using bitbucket or github (and updating it) would help with pull requests 
=)

I'll double check that this doesn't cause any issues cross-platform then push 
the changes.
