WIP TrackVectorFitter compatible with use of TrackEventFitter

This should happen together with Brunel!286 (closed)

• TrackEventFitter can now run with either TrackMasterFitter, TrackVectorFitter or TrackInitFit configured with either.
• Both TrackEventFitter and TrackBestTrackCreator write the updated states information of the tracks to the Transient Event Store, if they are invoked with TrackVectorFitter.
• AlignedAllocator has been finally updated to a C++11 minimal allocator.
• ITrackFitter exposes operator() for batch track fitting. It now accepts a std::vectorTr::TrackVectorFit::Mem::Store& parameter in order to keep the updated states.
• Since updated states are stored in the TES, TrackVectorFit::FitTrack has dissappeared.
