User tracking

[SeanHayes]

I'd like to contribute changes that track the currently logged in user on FormModelData, and add options for requiring login for viewing and/or submitting a form. Is this something you'd be interested in? Would you be fine with me adding a FormModelData.user ForeignKey?

Thank you for the suggestion @SeanHayes. That sounds like a good plan :) If you have any questions or run into any problems along the way, please let me know. Feel free to ping me in #django on freenode
