Merging branch 'a.fixEmbeddedPython'  into 'main'.

Some problems with interoperation with Python are fixed in the `PyCore` module.

* `BornAgain.callScriptFunction` function is added to the PyCore module to call a function within a BornAgain Python-script.
* `Embedded.BornAgainPyFunctionTest` test is added to test importing a BornAgain Python-script.
* The produced Python scripts in `SampleToPython` module are fixed.
* In `SampleView` module, a GUI crash is prevented if the no Python script is selected or the selected script is empty.

Furthermore, `manual_winbuild.ps1` is updated according to the latest changes.

The script-importing with the GUI was tested under Linux and Windows with different Python versions installed via the standard Python installer.
