Bug 5474 should not use tool tips for labels
To be consistent with other preference pages, the debug preference labels for step filtering (filter sythetic methods, etc), should not specify tool tips. Instead, the relevant information should just be in the label.

try {
			dialog= JavaUI.createTypeDialog(shell, new ProgressMonitorDialog(shell),
				SearchEngine.createWorkspaceScope(), IJavaElementSearchConstants.CONSIDER_TYPES, false);
		} catch (JavaModelException jme) {
			String title= "Add type to step filters";
			String message= "Could not open type selection dialog for step filters";
			ExceptionHandler.handle(jme, title, message);
			return;
		}
	
		dialog.setTitle("Add type to step filters");
		dialog.setMessage("Select a type to filter when stepping");
		if (dialog.open() == IDialogConstants.CANCEL_ID) {
			return;
		}
		
		Object[] types= dialog.getResult();
		if (types != null && types.length > 0) {
			IType type = (IType)types[0];
			fStepFilterContentProvider.addFilter(type.getFullyQualifiedName(), true);
		}
