Made minor changes here, since the code seemed obsolete (using a separate span
instead of paper-input's  floating label, using type="text" which is not
applicable). I can move those to a separate CL if you prefer.

Thanks for pointing this out. It really helps (so I'm not trying to figure out
how this fits with the other changes).
