Due to some not understood error the compilation of the AnalysisTreeQA package
fails suddenly. No changes were done. Since the problem affects the
compilation of CbmRoot it was decided to switch of the compilation till the
problem is understood and fixed.

Don't download the external packages when running the code format checker.
This improves the run time from more than 4 minutes to less than  1 minute.
Test each file individually such that the results on CDash are shown for each
file separately.

This version is an exact copy of the last revision of the trunk branch
of the old SVN repository of CbmRoor at
https://subversion.gsi.de/cbmsoft/cbmroot/trunk
The old SVN repository will still be available for read access.
