Commit [1] added the support for images with a link set on them in grid mode. As a follow up, this commit does the following: - Removes the `!important` from the grid image anchor CSS rules, as they were not really needed. - Checks if the image has a closest `o_grid_item_image` column instead of checking the parent in the `GridImage` options. Indeed, this class already guarantees that the image is well a grid image; we can therefore simplify the code. It also removes a comment that was forgotten in commit [2].
