Use a different color for folder icons in file dialogs

This makes them easier to distinguish from files for quick
visual grepping.

This can also be used in projects by setting the FileDialog "folder"
color. The default value (`Color(1, 1, 1)`) has no visual impact,
for compatibility with existing projects.
