Add URLs to bibtex list when possible

[ihnorton]

Now that we have the citations list online:

http://slicerdmri.github.io/citations/

It would be useful to add URLs to the bibtex file whenever we come across them so that a link can be included in the generated list entries. (see example: 33b2188)

Okay, I’ll update the bibtex file to include the link.

I don't think we need to do them all now, just keep it in mind when you are adding/editing entries in the future!
