massimo tristano 799d3343e2 - Fixed various crashes caused by deleting expressions inside Material Function as well performing undo/redo operations after deletion. ...

- Removed dubious code in MaterialEditor.cpp that prevented orphaned nodes to be deleted.
- Unified calls to Material->Modify() to MaterialModify() to make sure Modify() is called on the material and its editor only data, as well as the edited material function (if any) and its editor only data.

#rn Fixed an issue that caused frequent crashes when performing delete, undo, and redo operations on Material Expressions, especially when these operations were applied to Function Inputs while a material using the Function was open in the editor.
