[ beautifying ] make groups snap to grid

[JorgeR81]

When I move groups, the node positions don't match the grid anymore.

So, I need to select and move all the nodes to snap them to the grid again. And then, I need to "Fit Group to Nodes", to match the group box to the grid.

To make this easier, when the "snap to grid" option is enabled, it should also be applied to groups.

Thanks
