Skins did not offer a simple way to get back to normal speed
once user had clicked several times on either slower or faster
rates.

This patch automatically resets rate to normal if user presses play/pause
when an input is already launched. (as suggested in trac #2412)

This patch redefines the method associated with visibility
to ensure that the latest text is displayed when
the text control gets visible

image.jpg is a very small 1x1 image.

access_t::info.i_pos must always be updated to allow icy-meta and seeking
support.

We already do that in contrib makefile.

parsing is simpler.
