- Invoker methods can now be called directly without the need to mock the invoker decorator function.

- Added `functools.wraps` decorator to invoked functions of service classes.

- Added a list of safe modules that may never be removed from the list of already loaded modules. Removing the module 'typing' from the list would cause a RecursionError exception since Python 3.6.1.

- Additional improvements to network connectivity issues to not get stuck in waiting state.

- Improved SNS+SQS draining / restart when network connectivity has been lost or temporarily suspended. Would improve situations when development machine has been in hibernation.
- Replaced deprecated logging functions to rid warnings.

- Support for a "generic" aws dictonary in options that can hold region, access key id and secret to be shared among other AWS resources/services.
- Updated aiobotocore / botocore dependencies.
- Gracefully handle and discard invalid SNS/SQS messages not in JSON format.
- Corrected issue where watched directories with "similar" names as settings would be ignored.
