Translations:PropertyLink: InList and OutList/4/en

The dependencies are expressed via a special class of Property types, namely the PropertyLink:
 * PropertyLink: this allows a feature to link to another single feature within the same document.
 * PropertyLinkList: this allows a feature to link several features
 * PropertyLinkSub: this allows a feature to link a single feature and additionally reference sub-elements. Example: If you want to model a pocket for the needed sketch, then it's important to know on which sub-element (e.g. Face6) of the linked feature it must be mapped to.
 * PropertyLinkSubList: this allows a feature to link to several sub-elements of several features.
