core: bridge can now be changed in conf
by default DBus bridge is used, but this can be changed in sat.conf's DEFAULT section using "bridge" option.
bridge can be "dbus" (or equivalent "dbus_bridge") or embedded at the moment.
Bridge name used is saved in SAT.bridge_name, and load_bridge method can be used by frontends.
