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.

if (monitor.isCanceled())
					throw new OperationCanceledException();
				project.open(IResource.BACKGROUND_REFRESH,
						new SubProgressMonitor(monitor, 1000));
			}
		};
		
		try {
			getContainer().run(true, true, op);
		} catch (InterruptedException e) {
			return false;
		} catch (InvocationTargetException e) {
			
			Throwable t = e.getTargetException();
			if (t instanceof CoreException) {
				if (((CoreException) t).getStatus().getCode() == IResourceStatus.CASE_VARIANT_EXISTS) {
					MessageDialog.openError(getShell(), "", 
							"" 
					);
				} else {
					ErrorDialog.openError(getShell(), "", 
							null, ((CoreException) t).getStatus());
				}
			}
			return false;
		}
		return true;
