Test now covers Mode 3DMean, too. The corresponding filter (mitkNavigationDataToPointSetFilter) had to make more flexible. The problem was, that the filter read in one navigation data every 25ms, which could easily lead to a test failure. Instead the filter now continuously checks, if a new navigation data is availabe.
