Add some basic memcached handling to status_network
Status_network can't be a subclass of Memcached_DataObject -- the latter is too entrenched in Laconica's memc handling functions, which aren't loaded when Status_network is running! But the importance of caching these values can't be overstated. So, a considerably slimmed-down version of the Memcached_DataObject code is transcribed into Status_network.
