suppress '0 seconds ago' update values
add processing feedback to sensor updates
increase "focus lost" timeout to 200ms

apparently 100ms are not enough time for the browser to blur the input
box and send a click event to the button, but 200ms are. if anyone has a
better solution, please let me know.
relocate "About" button to the right of the layout
localization, first pass
