Added WebSocket support to the mine request

[dafnarosenblum]

Mining a block might take a long time. As a result, a server response might block the client from performing further requests or even cause a timeout error. To prevent this from happening, we replaced the current REST API of /blocks/mine with a websocket interface. This way, the server can notify the client right after a new block was created. The client then closes the connection.

The pushed files include the new implementation (14_websocket.ts) a websocket client (14_websocket_client.js) and a bash script which executes the client file (14_websocket.sh).
