This fixes the following name collisions:
* Compositor Box/Ellipse Mask node: `width` -> `mask_width`
(also renamed the `height` property accordingly)
* Shader AOV Output node: `name` -> `aov_name`
* Geometry Color node: `color` -> `value`.
Those are breaking changes unfortunately, because looking up those property
names yielded the node-specific and not the common property. Therefore, this is
targeted at `main` instead of `4.1`.
