Masking local.py errors

[jameshume]

Hi Chaps,

Thanks for this great resource to learn Django with. Its is really useful and well written. I'm just starting my journey and one thing I found useful was to change the "except:" in settings/__init__.py into "except ModuleNotFoundError:". The reason for this was that if I made a mistake in local.py it was quietly being ignored, not because it didn't exist but because I made an error. It would be nice if those errors were reported back rather than masked :)
