Improve Custom material assets loading

Some tweaks that focus on minimizing presentation loading time:
- Prevent adding duplicate search directory.
- A fix in matchCaseInsensitiveFile() method to use a cleanPath for
comparison (I think this method should be removed altogether).
- Other minor tweaks.
