get capabilities request ... :
http://localhost:5000/wps?request=GetCapabilities&service=WPS

... only shows en-US language:

<wps:Languages>
    <wps:Default>
      <ows:Language>en-US</ows:Language>
    </wps:Default>
    <wps:Supported>
      <ows:Language>en-US</ows:Language>
    </wps:Supported>
  </wps:Languages>

But the pywps 4.2.4 version should have language support:
geopython/pywps#510

@huard tests are failing. translation process needs to be added to the test_wps_caps.py test.

Translation is not shown:
http://localhost:5000/wps?request=DescribeProcess&service=WPS&version=1.0.0&identifier=translation&language=fr-CA

... title in English, not French:

<DataInputs>
      <ows:Title>Input1 number</ows:Title>

... it works when using the fr-CA as key in process definition:

LiteralInput('input1', 'Input1 number',
                         translations={"fr-CA": {"title": "Entrée #1",

There was a mismatch between process and config. Should work now.

@huard sure. I add it and make the merge.

@huard I have added support for de-DE and fixed the tests and test.cfg config.
