Fixed rivetvm exit code propagation in case of crash to print proper error message on the job failure reeason.

Swithced error messages off for inconsistent mother-daughter relationships for version 8.3+, since Vincia's antenna-like mother-daughter relationships not yet understood correctly by HepMC interface.

Reduced requested merging levels in several sherpa run cards in attempt to mitigate problems with long-running/aborting jobs.

Added Cut_Core 1 keyword to Sherpa ee -> 4b run card to force it to be treated as a higher multiplicity process in the merging; otherwise full of divergencies regulated only by b mass (which may or may not be zero). Thanks to Marek Schonherr for the bug fix.
