Subject: Change the way attachments are persisted. Editing a worn attachment
 will now save properly, as will the results of a resizer script working.
 Attachment positions are no longer saved on each move, but instead are saved
 once on logout. Attachment script states are saved as part of the attachment
 now when detaching.
