fix the compiler error i.e. in Pythia8_i.cxx use set_free_parton_exception instead of set_free_parton_warnings

* Include destructor in CompoundUserHook
* Remove allowedTunes check from Pythia8_i (is carried out by recent Pythia versions)
* Remove more cruft such as legacy HepMC units converson
* Add function addLHEToHepMC, which adds a HepMC-ified copy of the LHE record to the HepMC event
* Added CompoundUserHook to run multiple user hooks simultaneously (with caveats!)
* Reduced printout of event listing
* Update name of default PDF to reflect proper cteq6l1 naming
* Removed unused  * VetoedShower.cxx
* PTRelVetoedShower
* PoWHEGVetoedShower
* ISRVetoedShower
* QCDVetoedShower
* Started cleaning up legacy commands for 8.1X series and old PDF syntax
* Added mHat reweighter at request of tau CP group

Offline beamspot sweep part 3

This fixes an occasional crash when reconstructing toroid-off data.
The problem turned out to be that the standaloneRefit method is not protected against the 0 magnetic field case.
Since the refit is not really necessary for processing toroid-off data, the simplest solution is to turn it off.
Since this fix only affects toroid-off data, no FT0 violation is expected or observed.
Results of running the Tier0 tests can be found at /afs/cern.ch/work/w/wleight/public/MuonSW/ATLASRECTS-4060/.
(Note that although the log indicates there were changes in MuonCombinedBaseTools, there were none, I simply checked out the package by mistake and forgot to remove it.)
