Evan Prodromou e2e6bbb298 caching layer for DB/DataObject
I added a new class, Memcached_DataObject, that will (optionally)
fetch data out of a memcached server if it's available. This only
works on 'staticGet'.

Methods that write to the database (insert, update, delete) will clear
and set the cache correctly, too.
