    GsShellCategory: fix a formatting issue
    
    We don't want the subcategory list to grow super-wide while there
    are no apps, temporarily. The solution is a little hacky, but
    works: just put placeholders there, then the homogeneity of the
    grid will do the rest (empty columns defeat it).
