[Observium] Missing rebuild buttons for groups and alert checkers

Hi,

We use Observium groups extensively, often nested several times. Our alert checkers then reference these groups. After making changes to a group, including by adding a device, we used to force rebuilds of the groups (possibly several times) and checkers so the changes would propagate all the way through. We are on the latest stable revision (r13582) and the rebuild buttons are no longer available in the UI (possibly removed in r13391). What should we do now when we need to forcibly propagate changes?
