add support for quagga ospfd raw config support

rewrote the not-completed raw config support for ospfd.conf and zebra.conf to support stuff like zebra static routes and more complex szenarios.

hint: you must once fill out the assistent configuration otherwise the later parts like generate rc-scripts or carp detection won't work. but the generated ospfd/zebra config will work.

I've added the raw ospfd.conf and zebra.conf as output of the status page to get more details.
