Add test to dump hits from MultiSegment-MultiCollections example. Investigate issue: https://github.com/AIDASoft/DD4hep/issues/141 for details

UserParticleHandler: fix logic for long lived particles with pre-assigned decays that end in the calorimeter

fixes an issue where the MonteCarlo history becomes inconsistent with the history from the generator because the original particle entry is not updated

Moved LEFT_DETECTOR and PARTICLE_STOPPED

remove clearing of status (no longer necessary)

Fix typo in docstring
Geant4ParticleHandle: add printout of status bits in dump4

Fix hundreds of std=c++11 compiler warningsAllow to change compiler settings in cmake/DD4hep.cmake valid for all packages.Watch out for CMAKE_CXX_FLAGS in cmake/DD4hep.cmake.Move to use Boost spirit::phoenix version 3. ---- Prepare for ROOT 6

No code changes. Common code formatting removing tabs, replacing with spaces (tab-size=-2) + emacs reformatting.
