Begin reimplementing without QuickDialog.

This should be a cleaner design over all. I used QD initially to throw together a prototype (which I did in literally less than three hours), but I wouldn't use it in production in a case this simple.
Add some design notes.
Add JONetworkClient and JOServerDirectory.

The latter is mostly implemented, and the former is just a shell.
Add an initial, untested model with AFNetworking.
Get the initial table view controller loading everything.
Set the delegate and listen to the refresh control.
