Run from source on Windows with wxPython 4.1.1

I wanted to give it a try to PySpy and, as I have many Python things installed on my Windows, I wanted to run it from the sources (I was only missing pyperclip).

However, I am running wxPython 4.1.1 (I think it is the required version for Pyfa) and I could not run PySpy correctly. It seems the API has changed. So I fixed it while keeping the old code. However, I did not test it with wxPython 4.0.x.

It works flawlessly now with wxPython 4.1.1 on Windows (not tested on Linux, I should have...).

Thank you for this. When I find the time I will test if it still works with 4.0.x and on Linux. Otherwise it would also require raising the base requirements.
