Editor debugger now always handle connections.

Browse Source 
The editor debugger used to only take the first client connection,
leaving potential new connections hanging until TCP timeout.
This caused a lock after some time when running multiple game/editor
instances, as the client will fill the write buffer, and then lock until
timeout (as the editor server would never read from that socket).

The editor now drops new connections immediately if it is already
connected to a client.
