Cactus should not abort when parameter is set twice in parameter file, to the same value.
Currently, Cactus aborts when that happens. While this is most certainly an oversight by the user, aborting is just annoying the user by stealing queue-time. I propose to make this a lvl-1 warning instead. If I set a parameter twice, to the same value, I certainly would like to have that parameter set to that value. Cactus should complain, but not abort because of that.
This would have to be changed most certainly in src/main/SetParams.c in a couple of places.
