[patches] remove RtTableTunnel* for olsrd6

For olsrd6 SmartGateway is deactivated for this reason we do not
need an tunnel table.
[patches] redirect only if no password is set

redirect after first boot only if there has no password been set otherwise
the redirection will not work.

Use http.redirect instead of javascript so users without javascript can actually
use the wizard. Reason why this was not working was misplaced <%+header%>.
move default values for olsr and network in own packages
