Before not giving any command didn't really give much feedback beyond "invalid arguments". This adds a basic usage message, and tells people that you can use "boringproxy server -h". I moved the "Starting up" log message because otherwise that would get printed when asking for "server -h". I also added error checks for the flag parsing; I think this isn't *strictly* needed, but I remember running in to problems once by omitting it (although I've forgotten what that problem was, exactly).
