Merge branch 'move-timeago-to-vendor-dir' into 'master'

move timeago.js to vendor directory

## What does this MR do?

moves timeago.js into `/vendor/assets/javascripts` for consistency with other external javascript libraries.

make sure timeago still works as it should...?  I don't see how this could have broken anything.
