Attachments continue to function after the parent topic is moved now.

Changed the signature of AttachmentStore.Add
Added the MoveTo method to AttachmentStore.
Added the MoveToByExtra method to AttachmentStore.
Don't forget to actually add the pre script for topic_c_edit_post x.x

Added the extra column to the attachments table.

You will need to run the updater / patcher for this commit.
