Connect Notes and Files to Contacts as well as Bookings

Right now, if I upload a file for a particular booking, such as a photo ID, that file is not associated with the contact that it is for. So the next time that contact books, I have to search for their last booking to get that ID. Same is true with Notes.

It makes sense to me that this needs to change so that there is an option to have files and note connected to particular contacts.
