Ability to provide a reason when deleting a page

When we delete a page we can:

• delete it with the possibility of restoring it (moving it also in the 'Recycle Bin');
• delete it definitively.

When an user deletes a page he usually doesn't need it anymore and doesn't care anymore about it.

There are some less common use cases when:

• the page is deleted because it has been moved to another space;
• the page needed to be renamed;
• the user wants to give a note/motivation about deleting the page (example: notifying the Admin to permanently delete it);
• etc.

In the screenshot (deletedMessage.png) the use case is that the page has been moved, but this information is nowhere visible.

An improvement would be to give the user the ability to leave a reason for the deletion, like in this case the user could have mentioned that the page has been moved and the new location of the page.

Just like we have for the 'Save' feature the 'Version Summary' that is synchronized with the 'History', the Deletion message would appear in the Not found template.
