Some properties of List component do not display a translated name

The 'cssClass' and 'bgColor' properties of the 'List' component in the archetype do not show their translated display name, but the raw parameter name.

Steps to reproduce:
1. login to the archetype CMS
2. edit the only channel
3. drag the 'List' component in the container in the home page
4. click the dragged component to open its properties

Expected: the 'Layout' section contains two parameters with the names 'Css Class' and 'Background Color'
Actual: the 'Layout' section contains two parameters with the names 'cssClass' and 'bgColor'.

The names are also the same in all CMS languages, but they should be translated just like the other parameters.
