Changelog:
2007-03-27 1.2
* Removed the signs from the total count of new installs or comments
* Redid the sorting so that the most interesting scripts should be on top,
where intresetingness is measured in the number of new comments.
2007-03-22 1.1a
* Fixed a bug with humanized times (in the last 1 hour => in the last hour)
2007-03-22 1.1
* Humanize numbers (10000 => 10,000)
* Show humanized time since last check (1 hour ago etc)
2007-03-21 1.0
* First version
