Added: reteclock works on Android TV. It appears on the TV home screen with a
banner of its own, and the remote drives it: the centre key starts the timer and
stops it again, held down it opens the menu, and up and down dim the screen and
give it back. Back still belongs to the television.

Added: every button in the app can now be reached with a D-pad, a remote or a
keyboard, and shows a ring when it is the one being pointed at. Most of this app's
buttons are drawn by the app itself, and a drawn button that answers a tap did not
exist to anything but a finger.

Added: a margin for televisions that cut off the edges of the picture — in the
general settings, off unless you turn it on. It moves the clock, the date line, the
saying and the timer's bar in by a twentieth on every side.

Changed: on a television the timer no longer offers Vibrate, since there is nothing
there to buzz with. Your stored answer is untouched, so a phone still vibrates.

Fixed: one activity was declared twice in the app's manifest.
