Adding limit for active apps.

Add an overall time limit for all apps, including ACTIVE apps. Right
now, the default is 4 hours per day, so apps can only have their jobs
running for a maximum of 4 hours in a rolling 24 hour window.

Also fix calculation bug where an app could be brought back into quota
despite having less than the quota buffer time available.
