Check if port is in use #63

I was working on server while in background another instance was started listening on same port (UDP 53). This caused script to finish without showing me any info. It took me a while to discover what was the problem. We should check if port is in user before calling $loop->run() and throw exception.

Diving into React's code, it looks like it should be throwing an error if a port is in use, but it doesn't seem to. But in anycase, think this is something to put on whoever is implementing the project.
