UIViews, no medallions, hide on close, Cocoapods

I needed all of these things in a recent project, so here's my set of changes that address many of the outstanding issues. In order for the Cocoapods thing to work, you'll want to tag your Github repo. I'd be happy to submit the spec to the Cocoapods project after you merge it. :-)

Thanks a ton!
