This involved a significant change in event handling for automation region views, but it brings it into line with how it works for other things. On button press we initiate a drag, then if no motion occurs, the Drag returns false during finalization, and only then do we continue through Editor::button_release_handler() to eventually end up in ::add_automation_event(). Although it is a substantial change, the fact that it now works the same way for audio regions, automation regions and automation tracks seems like a definite plus.
