A crude first draft a link creator for QueryUs

I drafted this up this afternoon. Fill in the fields and it creates a URI encoded link that sets everything up for QueryUs. It's still pretty rough. It does the bare minimum of error checking and there are certainly more elegant ways to get the job done. But it should make it easier to for teachers to play around with the tool.

I kept everything in separate files so that I didn't mess with Luke's mojo. We can eventually merge everything in together.
