As a content manager I'd like to know how often my page is linked to from other pages, so I have an idea of the ramifications of unpublishing or deleting it.

Interface-wise I'd expect this to work the same as the document and image stats. As with images, we wouldn't be able to search the codebase for direct uses of the page (e.g {% slugurl %}) but we should be able to find pages linking to it in the database which is better than nothing.

Adding this to the interface has some design issues as there is little available space for the indicator.
