#3 On Scheduler close, reschedule builds

[Eric Woolhiser]

Currently the reschedule function is only called at build end. It is possible (and even likely) that the user will schedule a new build prior to the build already scheduled:

For example:

A build is scheduled for Mon, Wed, Friday at 01:00. The build completed on a Wednesday morining and reschedules for Friday at 00:00. On Wednesday at 10:00 the user schedules an additional build for Thursday at 01:00. The reschedule function is not called, so the next build is still scheduled for Friday 01:00, and the Thursday build will be missed.
