This reverts commit 0e3881d8d79b81faa514669fa2836e415dcc5c95.
With the removal of moment.js, dates and times are no longer formatted
using the native locale. This allows the browser to format if the
functionality is available (Everyone but Safari).
Also included is a correction in relativeTime. Times in the future were
being displaed incorrectly -xxx seconds, and the in/ago verbage was
reintroduced.
