    Make Gail work with custom treemodels
    
    Gail did set the role to ATK_ROLE_TABLE for anything that is
    not a GtkTreeStore. The propery way to do this is to look at the
    tree model flags for list-onlyness. Bug 580291.
    (cherry picked from commit 2686af2fbb3cd12bb5437837c891d302a0674496)
