Client Update + Telnet accessibility

Client Updates:

• Added sounds for STUCK and HOME command.
• Added sound for slipping on ice
• Added sound on death
• Added a client handshake to tell the server you're in the Godot client specifically

Game Updates:

• ANSI color mode has been re-enabled for Telnet clients that are not the custom Godot client. You can now connect to the game in any Telnet-enabled terminal or MUD client (such as Mudlet) by connecting to 73.198.76.230 on port 1338. The pre-alpha server will remain at that address unless otherwise specified. If it is not responding, the server is likely temporarily offline.
• Note: Telnet play is still a little rough, especially on login. WASD movement keys/commands still apply. If you are playing in a terminal environment, such as on Linux, you can enable "raw input mode" to send keypresses automatically rather than pressing enter after each command by typing "raw" as a command. In raw input mode, you can use . or / as escape keys to type multi-character commands like you would in the Godot client input line.
