Release 1.6:
Added default action is center button is clicked with no action in progress. Timer is started. Center button stops/starts the timer, long click center button removes it.
Unreasonably fast lap button clicks are ignored on stopwatch actions. If there are existing lap times and the new lap time is less than a tenth of previous times, the click is ignored.
Fixing memory problem that sporadically caused crash on exit; fixing send of saved events to clean up overwriting of persistent data store.
