added link to JS/jQuery mini-project solution by me (RebootJeff)

I caught a weird jumble at the bottom of the document. I did a fetch/merge upstream before editing, so it should've matched the original (which does not have the weird jumble). Before I fixed the madness, there was a line that read "<<<<<<<<<HEAD" and a line that said "upstream/master" so I think there was some kind of issue when I did a fetch/merge upstream.

Hopefully it's all good though. The diff comparison below looks right.
