-0.01: First release
-0.02: Bugfix time: Reset minutes to 0 when hitting 60
-0.03: Fix distance >=10 km (fix #529)
-0.04: Use offscreen buffer for flickerless updates
-0.05: Complete rewrite. New UI, GPS & HRM Kalman filters, activity logging
-0.06: Reading HDOP directly from the GPS event (needs Espruino 2v07 or above)
-0.07: Fixed GPS update, added guards against NaN values
-0.08: Fix issue with GPS coordinates being wrong after the first one
-0.09: Another GPS fix (log raw coordinates - not filtered ones)
-0.10: Removed kalman filtering to allow distance log to work
-      Only log data every 5 seconds (not 1 sec)
-      Don't create a file until the first log entry is ready
-      Add labels for buttons
