- explicitly set the tooltips since the one in the .ui file were not taken for QuantitySpinBoxes (workaround for bug https://freecadweb.org/tracker/view.php?id=4059)
- uniform the height of all LineEdits in the TaskAttachmentEditor.ui (the 3 angles were higher than the 3 movements)
- now the angles are sorted x-y-z
- added tooltips to clarify what e.g. the rotation axis of the yaw angle means (not only important for non-native speakers)
