App item URLs in the app item table

The Pages app has shown the URL of the page below the page name for a while. Now all app items do too. 

This is useful in a few ways including:

• Easily see what the URL is for the item in case you need to change it.
• You can now filter the table by the item URL to find specific items. Useful for finding an item to update when doing an SEO or accessibility audit.
