As per Jon's suggestion at the meeting, do not show the text boxes until
there is a script or rspec to work with. In fact, do not show any of the
rest of the page until the user provides something.

Also suggested by Jon, is to now use a read-only textarea when the text
is not writable, do what we do on the show-profile page instead; show
the rendered text inside a plain scrollable div.

I also messed with the button labels, try it you'll like it.
