#404 Add import of grid size from ocd files

[Matthias Kühlewein]

I guess that at least a partial import of grid characteristics should be not very complicated for ocd version 9-11.

Proposal: add to function OcdFileImport::importGeoreferencing
something like

        case 'd':
            double grid = param_value.toDouble(&ok);
            if (ok)
            {
                map->getGrid().setHorizontalSpacing(grid);
                map->getGrid().setVerticalSpacing(grid);
                map->getGrid().setUnit(MapGrid::MetersInTerrain); // MetersInTerrain is default unit
            }
            break;

Need a test file (or an existing ticket with test file).

I added three Ocad10 test maps, each with active grid, 100m, 250m and 500m grid size.

Following modification is working (thank you for the hints Kai):
