[Rivet] Jimmyless Alpgen+herwig+jimmy

[Gavin Hesketh]

Hello,
I've been looking at the AlpgenFHerwigJimmy interface in Agile. It seems 
that Jimmy is never called.
Jimmy is initialsed (by a call to FC_JMINIT() ), so you get the Jimmy 
header in the job output, but is never called in event generation, ie 
there is no call of FC_HWMSCT.

Probably the best way to call Jimmy in AlpgenFHerwigJimmy is to copy the 
makeEvent function from FHerwigJimmy, while keeping the call to FC_UPVETO.

thanks,
	Gavin
