[network] ServerInfo is only used on client - rename to ClientConnectionInfo

[francy51]

There is no clear way of knowing which of the IPs declared in Project Configuration the server is being built to host on. ServerInfo could be renamed to ClientConnectionInfo to clarify this situation

Turns out the server does not care what IP it is running on (only the port). Renaming of ServerInfo does still apply and would help clear up future confusion.
