Export all linked pages option

Currently, you can go to Settings/Export and select multiple pages to export.

This works, and the links resolve well.

However, as a user you have to "know" what all the links are.

Instead, it would be nice to export one page, and then have a checkbox "include linked pages".

Then it would go through, find the links, and be equivalent to the user selecting them all on the export page

Should be easy to implement, since you already support doing it manually.
