Allow to clone / copy / duplicate screen when creating a new one

For new screens now we have to define new screen and set all plugins and pages.

If we get a new screen form same model that we already have can be easier to use the previous as a template and dont start from scratch

On new screen it can offer the option to reuse an existing screen, provide checkboxes for selecting if it will reuse model, plugins and pages

This will allow easy way to configure new screens, from exactly same model or even with different models just reusing compatible plugins and pages
