Title: Add exception rule to converter configuration: fix #253

I added a method to write exception rules to converter configuration. Users can easily write a rule to match any keys except a given string like this:
```
{ "key": "*", "except": "name", ... }
```
This rule means the rule matches all keys except "name".
