[LH1781] Beta 17.0: Main Editor: Text Background & Margin Space Background

It seems some parameter of color scheme, important enough, was dropped while updating the Theme part.

Before updating to Beta 17, I used white background for the typing area and slightly darker (RGB 210,210,210) tone for the empty space around it. It was nice and comfortable.

After update, it appears that there is one parameter instead of previous two: if typing area is white, the margin area around it is white too (other colors give the same result), so there is no visual border between them, which is rather unpleasant. Please, put it back.

This has been filed. Thanks!
