+*
+ initialize the local IPC connection to Discord
+
+ what we need for rich presence
+ - send rich presence data to the client
+ - start spectating a session
+ - join a game party
+ - request to send rich presence data ('on discord client connected')
+
+
+ general usage
+ - initialize the discord connection
+ - determine if the user is a guest account
+ - shutdown / support timing out
