Show in the README what tiles can do

Two rows rendered from the firmware with a demo home: heating mode keys,
playback keys and a fan speed slider on double-width tiles, large values,
small sliders and pastel script and scene tiles, a digital clock, a timer and
an off switch on the Guition; the same kinds of tiles and previous/next for a
choice on the CYD.
