I added a lot of stuff! I fully set up exclude_interface to ignore inactive interfaces, and optarg, Along with a small list of other interfaces. I did some bug fixing, And looked into how netsukuku sets it's interfaces by default, And added some stuff to deal with that too.

I, Also, Figured out that, The entire exclude_interface function is probably unnecessary, And can be fully replaced with just check_excluded, Which would be much simpler, Easier, And elegant. Along with the fact that, It will probably just work.
