Feature/client socket adjustments (#212)

* Changed default listening port to something slightly more meaningful

* Removed TCP socket and made websocket the default option (as opposed to 'None')

* Updated template

* Updated ReceivedBuffer to allow direct message forwarding

* ignoring vscode directory

* Push messages mechanism for websocket client-clients

* Removed flawed chunking example

* ... but added bunch of websocket examples in return!

* Moves js example directory

* Cargo fmt

* Removed old listener code
