* Fixed: Layout editor not rewriting but overwriting previous config XML files, which in some cases results in invalid XML structure
* Script controller now supports object and node variable types. These can be added, removed, renamed, or re-assigned
* Script controller displays its expression for name and does not include constant variables

* Script controller lists target variables as inputs (it does not allow adding them, though, object vars should be used instead)
* Script controller object variables no longer accept scene nodes, these should use node vars

* Fixed: User-assigned parameter checkboxes do not change (integer or float) parameter values

* Refactored utility classes
* Fixed crash when a free camera is assigned to a viewport and schematic node preview is rendered
* Temporarily/experimentally using maxscript to create free and target camera because doing so natively produces cameras without visible viewport gizmos

+ Added missing files
