allow public access to socket and keep it open when requested

[Bersaelor]

Hey there, I've been using swifter for a while, but in my case I was always keeping the sockets open, to allow for stateful connections.
In my case communication is bidirectional, the phone acts as a sort of remote for the browser window.

The below are all the changes I needed from this project, would this be something worth merging into the main branch?

Hey @Bersaelor, could you give me an example of how you're using this?

Also, could you fix the merge conflict while you're at it?

hey @michaelenger ,

from a UX perspective the user only opens the page in their browser and then never interacts with the desktop pc/mac anymore, instead going across the room and controlling the website with their phone.

First I save the socket that is currently open when the website loads, like this:

 // during init
do{try httpServer.start()}catch{
log.error("While starting httpserver: \(error)")}httpServer["/"]=htmlHandler(filePathComponent:"/Web/index.html", context: rootContext)httpServer["/websocket-echo"]=websocket(
text:webSocket(session:text:),
binary:nil, pong:nil, connected:nil, disconnected:nil)}fileprivatefunc webSocket(session:WebSocketSession, text:String){guard text.hasPrefix("BTI$")else{
// if text doesn't start with 'Browser To Iphone', then it's not a socket message
session.writeText(text)return}
log.debug("message: \(text)")ifself.currentSocket ==nil{self.socketDidOpen()
currentSocket = session.socket
session.socket.didClose ={[weak self]inself?.socketDidClose()self?.currentSocket =nil}}guardlet message =RemoteScreenMessage(message: text)else{
log.error("text couldn't be parsed: \( text )")return}
log.debug("Message: \(message)")DispatchQueue.main.async{self.received(message)}}

and then when I want to make the currently presented desktop page change I do:

fileprivatefunc sendToClient(_ message:MessageToBrowser){letmsgString="....."
log.debug("Attempting to send msg: \(msgString)")
networkingQueue.async{guardlet socket =self.currentSocket else{return}letsession=WebSocketSession(socket)
session.shouldCloseSocket =falseif message.type.shouldBeRepeated {self.lastMessage = message }
session.writeText(msgString)}}

This is a cool idea, what do you think @Vkt0r?
