jQuery Prettydate Plugin

This plugin, originally written by John Resig, provides clientside date formatting in the style of Twitters timeline: just now, 5 minutes ago, yesterday, 2 weeks ago. This release extends Johns original release, providing support for internationalization and improving the API a bit: You can specify the source of the ISO-date, while not having to manually set up an interval to update the date formatting over time.
