Subject: * Remove redundant <scene> tag from individual object xml
 representation * WARNING: Until both regions upgrade to this revision, prim
 crossings from regions on this revision to earlier region revisions will not
 work properly * e.g. in the attachments cases, the attachments will remain
 visible but won't be individually detachable * This change may seem to have
 more costs than benefits, but I'm doing it because I can soon reuse this
 changed existing code in another context - it seems better not to proliferate
 similar but slightly different xml serializations.
