rework the internal scheduling so that all of the builds are queued up front, allowing for a variety of optimisations. Related work includes - disabling of the standard DependentTriggers - the display of a queue on the project home page. - assimilation of requests now occurs very late - at activation time rather than at queue time - numerous refactorings and the like.
