Reuse HTTP port for WebSocket

[fregante]

See:

• Reuse HTTP port for WebSocket fregante/GhostText#272

Relevant code:

nvim-ghost.nvim/binary.py

Lines 476 to 480 in bcebc1f

	def _websocket_server(self):
	while True:
	random_port = random.randint(9000, 65535)
	if not _port_occupied(random_port):
	return GhostWebSocketServer(LOCALHOST, random_port, GhostWebSocket)

In the current state of the code, it's not possible to run both the servers on the same port.

Both the servers that are being used in this binary (http.server and simple-websocket-server) try to occupy the port. So, running two servers on the same port isn't possible.

To do this, I basically need to write a whole HTTP server and a WebSocket server from scratch, which is a pretty big task that I don't have the time to do right now.
