WiFiServer - allow constructor without parameters

[JAndrassy]

with begin(port) available, the constructor doesn't have to get port. I hope you like the default port number 23.

After re-reading the official API, you're telling that

• Official and esp8266 Server constructor always have a port argument
• Server::begin() can have a port argument or no argument

So you're adding a constructor without argument for coherency with Server::begin(port), is that so ?

[JAndrassy]

yes. the newest Arduino libraries have it so I consider it now as part of the official API. (And users ask for it for years now)

default port 23 instead of 80 on other implementations is one of the spices used for the taste of this core.

I know :-)
