Added a new parameter "cutoff", to limit the number of days in the past for which events will still be shown.
Added a new parameter "sortdesc", to change the sort order.
Changed the code for identifying events ending prior to current date and changed the default template accordingly.
If you're not doing a fresh install, the new template is:
Date: {$item.start|date_format:"%b %e, %Y"} -
Time: {$item.start|date_format:"%I:%M %p"} to {$item.end|date_format:"%I:%M %p"}
{$item.long}
