I think that __import__ (or actually importlib.import_module) is the way to go 
here, and I've now changed both the storage and scheduling extension 
mechanisms to use it instead:

This means that I can remove some tools that otherwise need to be run, and so 
things become a bit simpler. It also removes the mutable already-installed 
file problem, too.

I guess I'll try and make a release fairly soon just to provide a well-defined 
output for you to look at again.

As always, thanks for the feedback!
