Add "Import/Export" Dev feature

[connerk]

Sometimes, it's nice to Import modules for development purposes that should not go into the production binary. an example is VBA-Test

it would be great to have an additional object in the config for dev-modules, similar to node's package.json.

I think that's certainly a good idea. It wouldn't be difficult to implement either. Another example use case I could think of would be a removable profiler module. I don't have any plans to work on this at the moment but If you feel comfortable implementing it, I'd wouldn't mind if you kept in touch.
