The implementation now terminates when the unix socket is deleted.
Currently we are unable to use fsnotify (on linux),
since it does not notify on the deletion of open files.
The implementation can now daemonize (on linux)
or be kept in the foreground by providing the necessary flag.
Program now terminates when the interface is removed
Increases the number of os threads (relevant for Go <1.5, not tested)
More consistent commenting
Improved logging (additional peer information)
And outbound routing
I am not entirely convinced the use of net.IP is a good idea,
since the internal representation of net.IP is a byte slice
and all constructor functions in "net" return 16 byte slices
(padded for IPv4), while the use in this project uses 4 byte slices.
Which may be confusing.
