Qt4: relayout the Toolbar Dialog for small screens.
Qt4: relayout the Toolbar Dialog for small screens.

The new layout is a horizontal layout, for people having a smaller screen than
1000 in height. This makes this dialog quite large, but screens are larger those days. If the dialog is still too big, please say so.
