when we have a combogrid that may be empty, we now show a little 'x' where the user can delete the content this is not shown when the field is not allowed to be empty we add a new css for this because triggers need a background image with a very specific layout: 110x22px which is 5 icons in one image for the various states (normal, hover, active, focused, focused hover) the icon is taken from the theme-crisp form/tag-field-item-close.png but rearranged to fit the size Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
