This commit turns the remaining blocking pop-ups in which the user can only click "ok"
into non-intrusive notifications, depending on the user preferences in settings.

- Better handling for exceptions originating in Python addConstraint.
- Refactor to reuse code for handling of exceptions

Recently the rendering order functionality was temporarely removed, as it interferred with the development of visual layers.
However, the release comes before visual layers are finished and can provide such functionality.
This commit reintroduces the functionality for the release.
In the Elements context menu (Sketcher task panel) the menu text for Sketcher_ToggleConstruction is "Toggle construction line", this should be "Toggle construction geometry". It is not just lines that can be toggled, and this is also the menu text in the main Sketcher menu.

Problem
=======
The popularity contest heuristic was designed to assume that removing one solver constraint from a redundant group would potentially satisfy it.
This means that for sketcher constraints comprising several solver constraints, the sketcher constraint would never be notified as redundant, but
always partially redundant (where the case may be that it is redundant or that it is partially redundant). This happens because after removing one
solver constraint, it may happen:
(a) that no other solver constraint corresponding to the sketcher constraint remains in the redundant group (so it is indeed partially redundant)
(b) that at least one other solver constraint corresponding to the sketcher constraint remains in the redundant group (so if all solver constraints
remain in the redundant group, the sketcher constraint is actually redundant). This happens because solver constraints of a single sketcher constraint
are orthogonal and consequently, a conflict (or redundancy) emanating from removing one of them cannot actually satisfy the group, as it has no effect
on the other.
Solution
========
When popularity constraint decides on one solver constraint, remove any other solver constraint of the same tag (i.e. same sketcher constraint) that is
present in the conflict group (case b). This does not affect case a, because the solver constraint that is not redundant is not present in the conflict
(redundancy) group.

A common operation is to toggle a group of geometry to/from construction. This happens often
in connection with carbon copy operations.
When this happens, geometry is often selected using box selection.
If there are geometry points (which are generally construction), and selection box is used, this
results in construction points being toggled to normal defining mode. This situation is undesirable
in 99% of the cases. It requires to reselect only the points and toggle them back.
When construction points need be made defining geometry (for example to use them as attachments), the
general workflow is to select only those points and toggle them.
In order to improve the efficiency, it has been decided to provide a special behaviour for construction
toggling:
1. Vertices will only be toggled to/from construction IF ONLY vertices are selected.
2. If there is a mixture of edges and vertices, vertices will be ignored during the toggling operation.
...the extra points created on rounded rectangles, it started to become a real pain when box selecting large amounts of geometry and having to keep changing the two points back to construction. New and existing users are completely unaffected.

Fixes an issue reported directly by Chrisb.
On overlapping points, such as due to coincidence, selection and
preselection (e.g. from the ElementsWidget) is not shown for those
points which are rendered first.
Solution: To raise the points to the highlight height.

I promised Uwe I would look into improving the information of the solver messages, including the abbreviation DoF.
I wanted to keep the effort by Paddle to reduce the width of the taskbar.
This commit introduces new explanatory tooltips for the hyperlinks, a different tooltip per type of information.
UrlLabel sets the tooltips automatically to the url text on change. This commit modifies the tooltip just after the change,
so that the meaningful tooltip is shown.

The scaling factor used was the one of the ViewProviderSketch, however ZoomTranslation uses its own scaling factor.
