4.1 Converted to Workflow

As of 6.99 we've converted the scheduler (runHourly.pl) and its plugins (sbin/Hourly/*) to the new WebGUI Workflow system. The program that replaces runHourly.pl is sbin/spectre.pl, which is always running and therefore doesn't need to be scheduled via crontab. To see the new API for the sbin/Hourly/* scripts, check out lib/WebGUI/Workflow/Activity/_activity.skeleton
