Added new methods.

* `Vector3.setFromMatrixPosition` is a new method that will set the components of the Vector3 based on the position of the given Matrix4.
* `Vector3.setFromMatrixColumn` is a new method that will set the components of the Vector3 based on the specified Matrix4 column.
* `Vector3.fromArray` is a new method that will set the components of the Vector3 based on the values in the given array, at the given offset.
* `Vector3.min` is a new method that will set the components of the Vector3 based on the `Main.min` between it and the given Vector3.
* `Vector3.max` is a new method that will set the components of the Vector3 based on the `Main.max` between it and the given Vector3.
* `Vector3.addVectors` is a new method that will set the components of the Vector3 based on the addition of the two Vector3s given.
* `Vector3.addScalar` is a new method that will multiply the components of the Vector3 by the scale value given.
