Title: Secondary Map Grid

The artist I'm working with asked for a secondary map grid purely as visual aid. You can toggle the secondary grid from the view menu and modify its properties in the preferences window. My engine uses orthogonal tile so I didn't spend a lot of time on the isometric/staggered implementation, but it appears to work.
