    Add an option to restore past broken behavor of the Events manager action
    
    Before r238915, certain values for the EventMask parameter of the Events action would result in no response being returned.  This patch adds an option to restore that broken behavior.  Also while fixing this bug I discovered that passing an empty EventMasks parameter would also result in no response being returned, this has been fixed as well while being preserved when the broken behavior is requested.
