+/**
+ * attach_move()
+ * This function performs an in place directory-to-directory move of a stored attachment or photo.
+ * The data is physically moved in the store/nickname storage location and the paths adjusted
+ * in the attach structure (and if applicable the photo table). The new 'album name' is recorded
+ * for photos and will show up immediately there.
+ * This takes a channel_id, attach.hash of the file to move (this is the same as a photo resource_id), and
+ * the attach.hash of the new parent folder, which must already exist. If $new_folder_hash is blank or empty,
+ * the file is relocated to the root of the channel's storage area. 
+ *
+ * @fixme: this operation is currently not synced to clones !!
