Remove "info"-toolbar. This used to be shown for browsers which don't
support retrieving text selections in a textarea. It prompted the user for
text and put the resulting wiki-markup in a textfield for copy&pasting.
However, this behavior confused many users, so the toolbar is now only shown
for browsers which fully support it (presently IE and Gecko).

Someone with some more time at their hands may want to experiment with the
latest versions of Konqueror, Safari and Opera to determine whether they
support retrieving selections so we can enable the full toolbar for those
browsers.
