Doomsday Engine

The objective is to make the engine always run in client/server mode, even locally in single-player games.

Completion of this feature is planned to be a milestone for incrementing the major version number.

Note: On mobile devices (iOS/Android), there still needs to be a way to compile everything into a single binary. In this scenario, the server and client would be running in the same process and communicate over a simulated network link. It would be necessary to share cached resources to avoid needless duplication. However, the majority of the engine can remain oblivious to this arrangement.
