* Fixed a NPE when trying to select a Node. Now you can properly remove/edit nodes
* "smartLog" now compares the hash across different instances (Two Material Previews led to duplicate log messages)
* Using smartLog for CompilationErrors now to not spam the log with 60 FPS
- better handling of errors in the material definition
- the navigator now properly refreshs
- the editor is reloaded when a change occur in the text file
