Little cosmetic tweak.

before:
```yaml
    # router configuration
    router:
        resource:             ~ # Required
        type:                 ~
        http_port:            80
        https_port:           443

        # set to true to throw an exception when a parameter does not match the requirements
set to false to disable exceptions when a parameter does not match the requirements (and return null instead)
set to null to disable parameter checks against requirements
'true' is the preferred configuration in development mode, while 'false' or 'null' might be preferred in production
        strict_requirements:  true

    # session configuration
    session:
```
after:
```yaml
    # router configuration
    router:
        resource:             ~ # Required
        type:                 ~
        http_port:            80
        https_port:           443

        # set to true to throw an exception when a parameter does not match the requirements
        # set to false to disable exceptions when a parameter does not match the requirements (and return null instead)
        # set to null to disable parameter checks against requirements
        # 'true' is the preferred configuration in development mode, while 'false' or 'null' might be preferred in production
        strict_requirements:  true

    # session configuration
```

could you add a testcase ?

---------------------------------------------------------------------------

This class had no tests at all, so I thought it's not important... I added one but I have not much experience in writing tests. Is it adequate?

I realized that the new numeric node type not supperted by the dumper at all.

looks good to me. However, you should edit the PR description: this is a bugfix

---------------------------------------------------------------------------

@stof done. Thanks!

@fabpot this should even go into 2.1 as it is a bugfix

---------------------------------------------------------------------------

by 1ed at 2013-02-17T11:44:08Z

@stof there is no ReferenceDumper class in 2.1

---------------------------------------------------------------------------

by stof at 2013-02-17T12:23:44Z

ah, it was directly in the command in 2.1. But the bug should still be fixed IMO

This PR was merged into the 2.1 branch.
