* Fixed vray parameters by adding custom MaxScript-driven rollouts (this makes the layout of the material longer though and needs more work)
* Internal refactoring

+ Added specialized icons for PFlow objects
+ Added custom entity layouts for a couple of classes

* Minor changes

* Nodes in synoptic views now have icon minimize button
* Fixed auto-layout restored in synoptic views after scene reload (even though AL should never be allowed in synoptic views)
* pflow source uses icon instead of object preview in schematic

+ Added missing files
