    Revert "Add a button to create a group layer to the layers dialog"
    
    This reverts commit d2e1f2ac7402916644e4362c7fa11698e5f80064. If we
    keep the layer group button in 2.7.0 people will expect layer groups
    to fully work and get mad when that is not the case. We can enable it
    again after the release.
