OpenAtlas

Like discovered in the last user interview there were some issues about the use of sources.
Most of these can be solved via using an artifact as an information carrier of the source. But because it wasn't the first time that we noticed users having issues there we should provide more information in the user interface.

• Text and/or button tool tips in the tabs of the source detail view to make clearer that these connections are only used for entities that are mentioned in the source.
• Example in the manual about using sources with artifacts as an information carrier of the source. Maybe also link it at the source detail view.
