Optional switch off for fatal error on decaying beam particles

[Juergen Reuter]

as these processes occur abundantly as partonic subprocesses of LHC processes, there has to be a flag to switch this fatal error off:

sqrts =    500.00000000000000     
Beam data (collision):
 b     (mass = 4.6000000 GeV)
 tbar  (mass = 178.00000 GeV)
 sqrts = 500.000000000000 GeV
| Integrating process 'prc1'
| Generating phase space configuration ...
Warning:  Intermediate decay of zero-width particle H+ may be possible.
|  t -> b W-
|  mass(t) =  0.1780000000E+03
|  mass(b) =  0.4600000000E+01
|  mass(W-) =  0.8041900000E+02

*** FATAL ERROR:  Phase space: Initial beam particle can decay
******************************************************************************
******************************************************************************
| There were no errors and    1 warning(s).

Some of the CATPISS tests e.g. cannot be run with that fatal.

Is this a defect or a feature request, I don't know.

This has been done in r1794. Closing.
