What to do about nested dialogs

[Polleps]

There are a few situations where you can open a dialog from another dialog. In general we try to avoid these scenarios but they do exist. For example when creating a resource inside you can create nested resources by selecting the 'Create: ' option in a resource selector. A dialog will open where you can create the nested resource. If this resource class happens to have a file property, A file selector button will be rendered that opens another dialog.

Nested dialogs are problematic because they are confusing.

There is also a bug where both dialogs are closed when the user closes one of them.
