Added support for defaultrouter, both as a variable and as /etc/defaultrouter.

Changed the everlenghtening list of "if [ -f /etc/hostname.foo ].." to a
loop which will do them all, and look for init-scripts for them as well.
perfect place to put your calls to slattach and such: /etc/start_if.sl0
for instance.
