Bug 81768 [Import/Export] Import projects wizard layout improvements
3.1M4 I found two small layout problems with the Import Projects wizard. 1. The Import Projects wizard does not call initializeDialogUnits(), and hence the "Browse..." and select/deselect buttons are not of the appropriate size. 2. The selection buttons create a layout but leave the default margins, and hence do not align correctly with the Browse... button.

			public String getText(Object element) {
				return ((ProjectRecord) element).getProjectName();
			}
		});
		projectsList.setInput(this);
		createSelectionButtons(listComposite);
	}
	/**
	 * Create the selection buttons in the listComposite.

	 * @param listComposite

	private void createSelectionButtons(Composite listComposite) {
		Composite buttonsComposite = new Composite(listComposite, SWT.NONE);
		buttonsComposite.setLayout(new GridLayout());
		buttonsComposite.setLayoutData(new GridData(
				GridData.VERTICAL_ALIGN_BEGINNING));
		Button selectAll = new Button(buttonsComposite, SWT.PUSH);
		selectAll.setText(DataTransferMessages
				.getString("DataTransfer.selectAll")); 
		selectAll.addSelectionListener(new SelectionAdapter() {
			public void widgetSelected(SelectionEvent e) {
				projectsList.setCheckedElements(selectedProjects);
			}
		});
		setButtonLayoutData(selectAll);
		Button deselectAll = new Button(buttonsComposite, SWT.PUSH);
		deselectAll.setText(DataTransferMessages
