They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
wxString::Format is redundant in a wxLogXXX call.
Error messages should generally be translatable.
Error messages should use generally consistent sentence forms.
The variables in the common settings struct are only updated on
save, so Python must use the ones from Pgm to get its values.
This does lead to the observation that Python's changes to the
variables do affect KiCad (they can break resolvers). So apparently
it can mess with us but we can't mess with it easily.
Also, improve the environment variable tracing infrastructure to capture
more changes.
Before this, the environment variables inside Python wouldn't reflect
the updates to them made after the interpreter was started in Pcbnew.
This will call into Python and set the variables when they are changed,
since Python can't synchronize itself when running in an embedded
interpreter.

Always check the return value of PyRun_SimpleString() for errors when a
Python script is run and show an error message rather than fail silently.
Enable Python interpreter I/O redirection in debug builds so that script
string errors will be shown when PyRun_SimpleString() is called.
Do not call PyErr_Print() after a PyRun_SimpleString() call failure. It
doesn't do anything useful.
Do not call Py_Finalize() after a PyRun_SimpleString() call failure. It
seems to cause Pcbnew to crash.
Phoenix doesn't have the same initialization as wxpython3 and so the
namespace doesn't get the wxApp() initialized to the existing instance.
In python, this is worked around by starting a new wxApp.
Unfortunately, this appears to overwrite the existing global instance
variable. The issue _appears_ to be in Phoenix but for now we work
around it by saving and resetting the instance pointer in the main app.
The downside is that Python likely won't be able to respond to events
from C++
