WP-34s port to DM42

[Nigel (UK)]

No new features but a bug fix: I discovered the other day that the battery-saving optimisations that were introduced last year (!) broke the stopwatch display. This is now fixed: updated .pgm files can be found in the usual place (i.e., here).

I've also posted this on the thread at the SwissMicros forum. I don't want anyone to find themselves without a stopwatch when they need one!
