Hugo Locurcio 725ff19636 Improve the AutoLoad editor UX
- Convert the default AutoLoad name to PascalCase when selecting a file.
- Disable the "Add" button if the path is empty or the name is invalid.
- Prefix the automatically-chosen name with "Global" if it would
  conflict with a built-in class.
- Replace the FileList icon with the Load icon as it better represents
  the action.
