Add Duration unit constants to quiver.time

[seaneagan]

Constants:

const Duration microsecond = const Duration(microseconds: 1);
const Duration millisecond = const Duration(milliseconds: 1);
const Duration second = const Duration(seconds: 1);
const Duration minute = const Duration(minutes: 1);
const Duration hour = const Duration(hours: 1);
const Duration day = const Duration(days: 1);
const Duration week = const Duration(days: 7);
const Duration year = const Duration(years: 1);

Usage:

if(stopwatch.elapsed > minute) ...

new Timer(millisecond * 500, () {...});

var inOneDay = clock.now().add(day);

Part of me really wants there to be a "one" or "a" prefix... @yjbanov ?

The part of me that likes shorter variable names has knocked the other part unconscious :)

Sorry for the churn. I'm clicking on buttons too randomly this morning.

I do think it reads much better with the 'a' / 'an' prefix. It also keeps them co-located in the docs, and is less likely to conflict with e.g. var day = dateTime.day. But I can switch it back if needed.

A very practical observation. A prefix SGTM then.
