-/**
- *
- * This is the POST destination for most all locally posted
- * text stuff. This function handles status, wall-to-wall status, 
- * local comments, and remote coments that are posted on this site 
- * (as opposed to being delivered in a feed).
- * Also processed here are posts and comments coming through the 
- * statusnet/twitter API. 
- * All of these become an "item" which is our basic unit of 
- * information.
- * Posts that originate externally or do not fall into the above 
- * posting categories go through item_store() instead of this function.

-		 *
-		 * When a photo was uploaded into the message using the (profile wall) ajax 
-		 * uploader, The permissions are initially set to disallow anybody but the
-		 * owner from seeing it. This is because the permissions may not yet have been
-		 * set for the post. If it's private, the photo permissions should be set
-		 * appropriately. But we didn't know the final permissions on the post until
-		 * now. So now we'll look for links of uploaded photos and attachments that are in the
-		 * post and set them to the same permissions as the post itself.
-		 *
-		 * If the post was end-to-end encrypted we can't find images and attachments in the body,
-		 * use our media_str input instead which only contains these elements - but only do this
-		 * when encrypted content exists because the photo/attachment may have been removed from 
-		 * the post and we should keep it private. If it's encrypted we have no way of knowing
-		 * so we'll set the permissions regardless and realise that the media may not be 
-		 * referenced in the post. 
-		 *
-		 * What is preventing us from being able to upload photos into comments is dealing with
-		 * the photo and attachment permissions, since we don't always know who was in the 
-		 * distribution for the top level post.
-		 * 
-		 * We might be able to provide this functionality with a lot of fiddling:
-		 * - if the top level post is public (make the photo public)
-		 * - if the top level post was written by us or a wall post that belongs to us (match the top level post)
-		 * - if the top level post has privacy mentions, add those to the permissions.
-		 * - otherwise disallow the photo *or* make the photo public. This is the part that gets messy.
