Title: navbar extension can be disabled

The navbar extension cannot be disabled because the ```addDefaultsIfNotSet()``` config call sets the default values.
This PR fixes this issue, the navbar can be disabled in the config.yml like this:

```
mopa_bootstrap:
navbar:
enabled: false
```

It's fully backward compatible, and enabled by default.
