David Robillard b27a3d99ac Remove "smaller" track height (basically just a broken version of small anyway).
Remove no-longer-necessary cruft related to non-editable track names (which do not exist).
Fix smallest height to be correctly padded (just large enough to hold the button row without ugly clipping).
Fix resizing of tracks when renaming (issue #4075).
