This commit adds the default theme context, which replaces the need to manually check the project and the default theme all the time; simplifies related code. It also adds framework for custom theme contexts, to be used by the editor. Custom contexts can be attached to any node, and not necessarily a GUI/Window node. Contexts do no break theme inheritance and only define which global themes a node uses as a fallback. Contexts propagate NOTIFICATION_THEME_CHANGED when one of their global themes changes. This ensures that global themes act just like themes assigned to individual nodes and can be previewed live in the editor.
