Polished exception handling when importing extensions:
- Warning about failed import is printed on one line.
- For this warning the [extensions] section key is used, because the value
doesn't have to be set.
- Whan a --traceback is requested, exit immediately to not mix up problems
when importing an extension with other problems.
