One Copyright Update to rule them all As many open source projects have started doing it, we're removing the current year from the copyright notice, so that we don't need to bump it every year. It seems like only the first year of publication is technically relevant for copyright notices, and even that seems to be something that many companies stopped listing altogether (in a version controlled codebase, the commits are a much better source of date of publication than a hardcoded copyright statement). We also now list Godot Engine contributors first as we're collectively the current maintainers of the project, and we clarify that the "exclusive" copyright of the co-founders covers the timespan before opensourcing (their further contributions are included as part of Godot Engine contributors). Also fixed "cf." Frenchism - it's meant as "refer to / see".

[Net] New replication interface, spawner and synchronizer nodes. Initial implementation of the MultiplayerReplicationInterface and its default implementation (SceneReplicationInterface). New MultiplayerSpawner node helps dealing with instantiation of scenes on remote peers (e.g. clients). It supports both custom spawns via a `_spawn_custom` virtual function, and optional auto-spawn of known scenes via a TypedArray<PackedScenes> property. New MultiplayerSynchornizer helps synchronizing states between the local and remote peers, supports both sync and spawn properties and is configured via a `SceneReplicationConfig` resource. It can also sync via path (i.e. without being spawned by a MultiplayerSpawner if both peers has it in tree, but will not send the spawn state in that case, only the sync one.

[MP] Allow multiple synchronizers per node. The same node can now be controlled by multiple synchronizers at once. Spawn visibility is composed in OR across multiple synchronizers (i.e. if any synchronizer is visible to the peer, the object will be spawned). Synchronizers controlling spawned nodes can now have a different authority then the one spawning the node, in that case, the spawn variables for that specific synchronizer are simply ignored (other synchronizers with the same authority of the spawner will correctly synchronize variables on spawn). The SceneReplicationState class has been completly removed, since it was bloating the implementation, the state is now simply stored in the SceneReplicationInterface.

Style: Harmonize header includes in modules This applies our existing style guide, and adds a new rule to that style guide for modular components such as platform ports and modules: Includes from the platform port or module ("local" includes) should be listed first in their own block using relative paths, before Godot's "core" includes which use "absolute" (project folder relative) paths, and finally thirdparty includes. Includes in `#ifdef`s come after their relevant section, i.e. the overall structure is: - Local includes * Conditional local includes - Core includes * Conditional core includes - Thirdparty includes * Conditional thirdparty includes

[Net] New replication interface, spawner and synchronizer nodes. Initial implementation of the MultiplayerReplicationInterface and its default implementation (SceneReplicationInterface). New MultiplayerSpawner node helps dealing with instantiation of scenes on remote peers (e.g. clients). It supports both custom spawns via a `_spawn_custom` virtual function, and optional auto-spawn of known scenes via a TypedArray<PackedScenes> property. New MultiplayerSynchornizer helps synchronizing states between the local and remote peers, supports both sync and spawn properties and is configured via a `SceneReplicationConfig` resource. It can also sync via path (i.e. without being spawned by a MultiplayerSpawner if both peers has it in tree, but will not send the spawn state in that case, only the sync one.

[MP] RPC visibility. Implemented using MultiplayerSynchronizers. If you didn't use the synchronizer visibility features, nothing changes. If you were using visibility, RPCs to broadcast should now behave as expected in most configurations (i.e. by sending the RPC to _visible_ peers). If you want to limit the visibility of RPCs for a node, add a synchronizer for it, and configure the visibility via "set_visibility_for" or by adding a visibility filter.
