Define Utils.formatRelativeTime() and use it

Browse Source 
Previously, relative times were formatted using formatElapsedTime()
(appending translations of "ago" to them), sometimes resulting in
grammatically hard-to-understand or unnatural localizations. Now we
use ICU's RelativeDateTimeFormatter, which uses grammatically correct
and natural localizations from CLDR data.
