materials library

Materials in the editor, 2-D and 3-D: the editor's own module for them (BuiltInMaterialsModule, which JustGameEditorPlugin brings itself), and the normal map maker (NormalMaps, over Pixels) for tools that make maps from pictures.

A module adds to the material windows through the workspace contributions of just_editor_core (WorkspaceIds.material, WorkspaceIds.material2D), not by importing this.
