Nodes should have the same name in the Add Node menu as their actual name, but the Spiral node is called "Curve Spiral". Since there is no ambiguity with another primitive node called Spiral, it can be renamed to that. This also fixes an issue with translation, where the node could not be translated since its name was never extracted to the translation files.
