Merged PRs

ISSUE1473: How do I tell ddsim about simulating my beyond standard model particle?
- #1474: PDGFile: more documentation to mention secondary vertices
ISSUE1472: DDSim creates an extra event when numberOfEvents exceeds HEPMC input sizebug
- #1471: Exit in signal handlers with code (128+signal-number)
ISSUE1468: SIGTERM results in 0 retcode

ISSUE1285: Memory Consumption of Sensitive Detectors
==> Should be handled as illustrated in PR1288. Intrinsic problem of the Geant4VolumeManager;
ISSUE1297: Possible to dump all available readout elements?
==> Possibly a copy of unsolved ISSUE580 from Valentin about enumerating all sensitive cells.
ISSUE1319: Problem with regexSensitiveDetector and volume IDs
==> Interesting use case for reg-ex sensitive detectors
having a VolumeMgr equivalent.
ISSUE1320: Replacing a Handle<Segmentation> which contains a MultiSegmentation with the underlying Segmentation
==> Unclear what he really means.
ISSUE1335: Uniform random picking of points on detector surfaces for noise studies
This problem is linked to #1297 and #580.
PR1240: Add multithreading support to ddsim
PR1304: SurfaceManager: lazily construct surface maps on demand (Leonhard Reichenbach)
PR1314: Cylinder segment surface (Armin Ilg)
ISSUE1373: Add GeneratorInfo to EDM4hepReader (Andre)
ISSUE1443: Make user particle handler extensible
---> Maybe we should take advantage and re-collect requirements.
ISSUE1458: XML file vs TGeoStored geometry in GenFit
New issues:
ISSUE1469: Memory leak in Compact2Objects / Detector concerning Headerbug
