Small script engine improvements

- Fixed script class name not visible in Component Editor
- Retain user assembly file system watcher (fixed deletion while handling events)
- Fixed crash when a scritp constains a List or Array (by ignoring them for now)
- Fixed Typo in Genericinst
- Scene: Invoke OnCreate for copied entity scripts
