Draft: contextengine: Implement support for rainbow parentheses
This is a quick implementation of a feature I really miss from VSCode: Colored Parentheses
This makes it easier to see where a block starts/ends.
This is a draft as I'm not sure, whether you even want to support it and whether GtkSourceView is the right place or whether it should be e.g. some Builder plugin.
That's why it's currently with a bit of hardcoding:
- Not disableable
- Hardcoded colors (And the color selection is more like "First colors I could think of")
- Check, whether we should re-highlight the entire document on scroll/movement, as currently the colors are "dancing"
