Fixes

[mpapierski]

This project looks unmaintained. I made some fixes in my fork to use this with Django 1.6+. Here is short TODO:

• [x] url patterns new style
• [X] md5 is deprecated since 2.5, use hashlib
• [X] better entropy for control value. (it should be uuid for true uniqueness btw)
• [ ] South support
• [ ] Check if it works with recent Dotpay docs
• [ ] Py3k support

More things will probably show up as I am trying to use this code.
