New keywords were recently added to GDScript, it would be cool if there was support for those in this plugin. Those keywords are `onready` (https://github.com/godotengine/godot/commit/30c12297dc6df7d35df140475c0cec7308aea77a) and `breakpoint` (https://github.com/godotengine/godot/commit/7d2d1442f83e6a7a57a1823a6cf5af53e5419d5f).
