Team Update: Multisite (Wednesday)

I worked some more on the patch we had for #19810. The original patch had features that exceeded our original scope (namely: the ability to bulk-add users). I removed that, cleaned up the JS a bit, and we now have a patch that can probably go in and be iterated.

Next up is making it work in the add-user-to-blog interface in the Network Admin.
