add a contribute.json file (bug 1074452)

I did my best to find all the data to populate the json file, but l'm assuming I'll need to make a change or two. 
Removed the view, updated to using static.serve from url as suggested. I did try to join settings.ROOT at one point, but kept getting a server error, didn't know which settings file to use, if DEBUG was set to True, etc. I'm learning...:-)
