Extend moment.js to return very short words for time differences. Same as moment().fromNow, but much shorter.

moment.fromNowShort.js

/**
* A little moment js "plugin" to allow very short relative times
* NOT: "26 minutes ago"
* BUT: "26m"
*
* Usage:
* var m = moment('2013-04-08 17:50:00', 'YYYY-MM-DD HH:mm:ss');
* console.log(m.fromNow());   // -> "3 minutes ago"
* console.log(m.fromNowShort());  // -> "3m"

Thank you so much for making this Open Source. We benefited greatly from this.

Huge thanks!
