Support Collapsible Nodes in Layout 
 An additional option "Collapsible" is available in the "Layout" options of every node. When this option is enabled, the node position and/or node size is not taken into account for layout when "Enable Rendering" property of a node is set to "false". 
 New methods have been added for setting/retrieving of the collapsible flag - Layouter::SetCollapsible and Layouter::IsCollapsible.
