Grid should be able to be turned on/off

Ideally there would be more options like color, size, etc. but the most important one to get started would be a hide grid option, so that it doesn't z-fight with your scene if you have a plane or similar in the origin.

It would also be nice to set the grid orientation. For example, I have a top-down shooter where the camera is locked on the y axis but moves on the x and z. I would like to have the grid be oriented the same way.
