attach_move() function created to relocate files or photos to different directories in the cloud area and photo albums without deleting and recreating (which would create a new resource_id and invalidate any existing links).

/**
* 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 !!
