The redraw function was changed to return a list [dist, ang] if the real argument is not True. With this list the action function 'knows' which units to display. This also made it possible to move the "self.ui." related stuff that was in the redraw function to the the action function.
I have also changed to tooltip texts by removing the article "The". This more in keeping with other tooltips.
The poles in the resetTrackersBezier function are in the CS of the geometric parent of the curve. Before using `p = obj.getGlobalPlacement().multVec(p)` the nodes have to be translated to the CS of the curve. Otherwise the effects of the curve's Placement would be added twice. See discussion: https://github.com/FreeCAD/FreeCAD/pull/4889
the global coordinate system. They should therefore not be translated from the LCS to the GCS.
Draft_PointArray and Draft_TwistedArray have Count problems:
1. Draft_PointArray: Count is always zero.
2. Draft_PathTwistedArray: Number of items is Count+1.
3. Draft_PathTwistedLinkArray: Count is increased whenever object is recomputed.
Also the first item in a twisted array should be unrotated.

Removed from the Utilities menu because they already occur in the Modification menu:
Draft_FlipDimension
Draft_Edit
Draft_Slope
Removed from the Utilities menu because calling the command from there instead of from the Draft Tray does not make sense:
Draft_AutoGroup
Removed from the "Draft utility tools" toolbar because the command is very rarely used:
Draft_Heal
Fix 3 issues with the Draft Tray layer list:
The layer list should display even if there are no layers so that the "Add new Layer" option can be selected.
"Project" and "BuildingPart" objects should be added to the list (depending on "AutogroupAddGroups" of course).
The "LayerContainer" object should not be added to the list. Although it is in fact a group, it is just too confusing.

Added is_group function. This function can also be used in gui_groups.py.
