Test of final state

[HDembinski]

This PR fixes the issues with DPMJET and PHOJET models, which didn't follow the decay settings controlled by chromo, and adds a test which checks that all particles which we expect to occur in the final state actually occur for all models.

Two exceptions are built into the test:

• SIBYLL-2.1 does not generate Omega- (and cc)
• UrQMD doesn't generate only Omega- (however this might be related to limited stats)
• The QGSJet family does not generate Omega-, Xi0, Xi-, Sigma+, Sigma- (and cc)

The PR fixes the following problems to make the test pass:

• UrQMD does not generate KS particles. Bug was fixes in our fortran middle layer.
• DPMJetIII and PHOJET were not following the decay settings requested. Bugs have been identified and fixes to DPMJET backported + submodules updated.
• Vitange DPMJET/PHOJET had the problem as well, and it was fixed in chromo. The minor version of both codes have been upped by one to reflect the minor change.
• All tests should pass with less XFAILs for decays in PHOJET/DPMEJT models

This PR closes #156.

So, I found the issues with PHOJET and likely with DPMJET decays, and the mystery difference between 19.1 and 19.3. I actually cleaned up these subroutines in 19.3, not perfectly, but there is some improvement :)

I need to backport 19.3 to 19.1 because no Omega- is definitely a bug.

@HDembinski Sorry, I hijacked your PR to make substantial fixed to the decays in all of the PHOJET/DPMJET models. I identified the issues and fixed them directly in the fortran codes and also in chromo. I can't request a review from you, but nonetheless I think you can do a review or comment if you wish.

I also changed the base of the PR to be the branch we're preparing for release.

Cool. Finally decaying particles will decay.
