The collections manager now stores a reverse look-up from the objects within its collections, to the collections that contain that object. This avoids the GetCollectionsContainingObject and GetCollectionsContainingObjects functions having to iterate the collections for each object queried, which can be a large win for large sets of objects. This also adds some functions needed for the quick asset management feature. [CL 2570748 by Jamie Dale in Main branch]
