* New settings screen, opened by long pressing the clock: show seconds on or off,
  date format (Jul 12 or 07-12), and start-when-charging on or off.
* The hour and the minute are now bold and as large as the screen allows. The layout
  reserves space for the smaller lines first and gives the rest to the big time; a line
  that would be too wide is scaled down instead of clipped.
* Months are three-letter abbreviations in both orientations.
* All text is white; the secondary lines are no longer dimmed.
* Turning the seconds off frees their line, and the hour and minute grow into it.
* The supported Android range is shown on the settings screen.
