Node2d globalPosition should be Vector2
In the generated godotapi, `Node2d`'s `globalPosition` is a `float64` instead of `Vector2`. I'm not sure where to file this, but in looking through the godot source code everywhere I see `get_global_position` it is a vector2/point2 type, not a float.

```nim
proc globalPosition*(self: Node2D): float64 {.gcsafe, locks: 0.}
proc `globalPosition=`*(self: Node2D; val: float64) {.gcsafe, locks: 0.}
```
