Adding a beforefeatureselected event to the vector layer events. If a listener returns false, the feature is not selected. The modify feature control now listens for beforefeatureselected and triggers beforefeaturemodified. If a listener returns false, feature modification never begins. r=elemione,ahocevar (closes #1427)
