Change authentication

[carson-coder]

Change authentication to support authentication in userspace instead of world space.

Adds

• Separate send / receive sockets

To Connect

• Connect to ws://localhost:5050/recv and get a id (8 digit hex number). This is the receiving socket
• Connect to whatever end point (eg. ws://localhost:5050/code) and send that id. This will be the sending socket
• Then the server will send [password] to the sending socket
• The sending socket will send the password
• The server will then respond with [correct] in which case the sending socket can start sending code. and the recv socket will recv the output
• Or the server will respond with [wrong] and close the socket.

The last four steps are the same authentication protocol as last time.
The authentication only happens on the sending socket.

Setup in game (TODO)

Connect to recv endpoint - world space
put id in cloud var - world space
read cloud var and connect to end point - user space

Sending Code

Put code in cloud var - world space
Read cloud var and send code - user space
recv code output through recv socket - world spcae
