    view-icon-controller: Allow background click around items
    
    The old grid view allows users to clear selection and to bring up the
    background context menu by clicking the blank space around items.
    
    In order to achive feature parity, introduce row and column spacing,
    increas outer padding and free up the extra space under the file name.
    
    Also, to avoid compensate for the added spacing, also remove the
    padding in flowboxchild.
