Increased test coverage for all collection classes up to the priority queue to 100%; SetParent() is no longer 'protected internal' as internal is sufficient in this case (.NET 'protected internal' is less restrictive than 'protected' or 'internal' alone); parenting collection now unsets parent for items that are being replaced; priority queue version check for enumerators (to protected against modification of the collection) now only happens in debug mode
