implement what I hope will now be the server side of directory sync, add viewsrc to item_photo_menu, and log what changed in import_xchan update objects so we can find out why there are so many updates when nothing _obvious_ has changed that should trigger it.

fix photo file browser
don't create a directory sync notification (entry in the updates table) if the site record was updated - without checking first to see if anything changed. This is causing lots of sync entries when nothing changed to warrant it.

use prepare_body in api calls to properly render content, add 'mode' to conversation templates so that themes can use the module context to suppress or show comments as desired

assuming permissions are correct, unobscure photo comments. Should probably make sure permissions are correct and figure out why some photo comments on public photos are getting stored with privacy. This probably requires that whenever we change photo permissions for linked photos/items we change the item permissions to match. They might be out of sync.
