Release 1.6

versionCode 7. public_html/ changed, so the service worker cache goes to
bgclock-v22.

Confirmed on device, from a debug APK over the top of 1.5: the settings kept
from 1.5 came back on the You row with the switch off; the gear stayed
reachable with the two bases set apart, which is the failure that would have
had no way out; each side ran on its own delay, including a player set to zero
starting on their reserve immediately; and a turn left running well past the
delay, force-quit and reopened, came back paused with the split still in force.
