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".

Adding a new Camera Server implementation to Godot. This is a new singleton where camera sources such as webcams or cameras on a mobile phone can register themselves with the Server. Other parts of Godot can interact with this to obtain images from the camera as textures. This work includes additions to the Visual Server to use this functionality to present the camera image in the background. This is specifically targetted at AR applications.

#include "camera_feed.h"
Texture refactor -Texture renamed to Texture2D -TextureLayered as base now inherits 2Darray, cubemap and cubemap array -Removed all references to flags in textures (they will go in the shader) -Texture3D gone for now (will come back later done properly) -Create base rasterizer for RenderDevice, RasterizerRD

Renaming of servers for coherency. VisualServer -> RenderingServer PhysicsServer -> PhysicsServer3D Physics2DServer -> PhysicsServer2D NavigationServer -> NavigationServer3D Navigation2DServer -> NavigationServer2D Also renamed corresponding files.
