New function for generating list of all connected clients

[Mathiaszero]

In ENetMultiplayerPeer, there does not seem to be a way to generate a list of all connected clients. There should probably be something like list_connections(max size) that would generate an array of all connected ids, with specifying an optional max value in case the server has a long list of connected clients. Because it is an array, the coder can count the array elements to get the total number also.

I believe you can use get_peers on MultiplayerAPI and then use get_peer or ENetMultiplayerPeer
