Subnets should be set as lazy='join'

Currently if one does a net-list tons of queries are issued against the
database as the default query mode is 'select' which performs a query when
the field is actually accessed. In this patch I change the the mode to
'joined' so subnets are loaded as the networks are loaded. Usually, there
are only 1 or 2 subnets on a network so loading this data shouldn't hurt.
This patch in my setup with 5000 networks reduces the net-list call from 27
seconds to 7! Woot Woot :)
