Make .views-grid-four class more flexible

[josephgknox]

Currently, the CSS class being used to style pages with the .views-grid-four class is removing the margin-right from every fourth item. However, this treatment is only being applied up until the 28th item, leading to it breaking upon the addition of the 32rd item (increments of four).

Suggestion: replace the current code with the following code, which targets every fourth item, without a limit:

.views-grid-four .views-row:nth-child(4n+4) {
margin-right: 0;
}
