[FEATURE]  Module to generate prepared APIs file for call tips and auto-completion in Python Console

I would like add this new feature to the python console.

As discussed long ago with Larry, it would be useful to add the ability to python console to compile the APIs files to generate a prepared APIs file used by QScintilla. This brings the benefit of speeding up the code completion and calltips when you use many APIs files.

@dakcarto: I used your script (editors_api.py) to do this, so if you get a chance, could you test this feature please?
