master: using an external seq() function
master: add a 'type' field for nodes
master: use "object" as table name

"node" was misleading, object is much more neutral
master: use PRAGMA journal_mode=OFF

We do not care about rollbacks yet. It is still a full DB write each
time.
master: use PRIMARY KEY directly
master: use the storable on old config
master: added "ignore" as value for use_node_name

This enables to just ask for the the default node, like what you
have when you ask with "list "

It avoids completely the node name mess, and just do what you think
it will do.
