Subject: [PATCH] [SIGNED-OFF] Bug 6716 Document deleteditems table

This patch documents the deleted items table. Some fields were left
undocumented because I was unsure of what data was stored there:

stack - might be linked to shelving number, but need confirmation
paidfor - pretty sure this is unused, but don't want to document it that way
