Add a new PLANE PRIMITIVE on the primitive tools

The new add primitives tool is AWSOME! But the PLANE primitive is missing.
This simples primitive will allow us to draw rectangles easily and it would be a nice way to add a primitive to inset windows, door frames and any simples shape to start the modeling process by drawing in 2D and after that extrude/ extrude manifold in 3D.

Also the default behavior of the tool should be the orientation in default, not in the surface because in general at least the simple primitives like Planes and cubes will be placed relative to the default orientation of the viewport.

VĂ­deo showing why this is a nice addition.
