iIn the element editor, every rotation is made around the center of the
scene, this is usefull when rotate several part but less when only one
need to be rotated, especially when it is the terminal part and we only
want to change the orientation.
This commit solve it. Now when only a terminal part is selected, the
terminal don't rotate around the center of the scene but change the
orientation.
The rotation, flip and mirror of parts are good features but always
rotate around the center of the scene and if the parts are far from the
center of the scene the behavior look inappropriate from the POV of user
(because parts move far from original position and can out of the view).
A good new features should be to solve it (rotate around the center of
the bounding rect of the selection) and probably extract the function
rotate/flip/mirror from the parts class and create a new class with for
only goal to calculate and apply these modifiaction trough an undo
command.
When reading and comparing Qt5-docs and Qt6-docs, I read,
that there are no differences in the functions!
So it is not necessary to have the differentiation
between the Qt-Versions.
Code compiles without errors or warnings for Qt5 and Qt6.
Now that the problem with the translations of keyboard shortcuts has been resolved and rotation using the space bar works reliably in principle, I took a closer look at the rotation function itself in the element editor.
I noticed, for example, that arcs can be rotated at an angle of 15°. This doesn't really make sense, as the “arc” part doesn't have the “rotation” property. There is only width and height.
And somehow rotating arcs didn't work well: start- and span-angles weren't adjusted.
Lines and polygons can be rotated in 15° increments, which doesn't make much sense, if other parts that can only be rotated in 90° increments are selected at the same time.
To make a long story short:
I reworked the rotation functions of the graphical parts so that now all parts are rotated in 90° steps around the origin! This means that it is now possible to mark several parts and rotate them around the same point at the same time!
In addition, the functions for mirroring graphic parts at y-axis (shortcut "M") and flipping at x-axis (shortcut "F") have been implemented.
I have saved the text elements for later!

In the part list widget, the terminal name is empty if terminal haven't
got name.
Now "terminal" is always displayed and if the terminal have a name the
name is appended to "terminal".
Example :
if the terminal name is 24 then the the part list widget show "terminal
: 24"
* Some types of elements need to specialize the setRotation method in order to behave correctly :
- PartTerminal needs to call setOrientation
- PartLine, PartRectangle and PartPolygon need a different rotation center.
