Subject: Various optimizations: o Add model_cache::get() which caches models
 avoiding duplicate lookups o Stop using ORM relationships for
 Item_Model::owner so that we can use caching o For Item_Model::xxx_edit
 fields, don't make them editable for guests o Other minor stuff.

These optimizations reduce the number of queries for a 9-photos page from ~200
to ~45.  Still way too many!
