I hope --soft or --hard option.

I use this gem in works. This is very useful when inserting master data in DB.But, sometimes I feel db:seed_fu is too strict. If any of invalid seed on route, I fail to insert data after it. this is a not a little flexible.
So, I suggest --soft or --hard option. when encount invalid seed, default of db:seed_fu output warning and ignore it. when execute with --hard option, in the same way as now, output error and finish Behavior. Or,vice versa (--soft option).
Finally, I'm sorry the poor English. I hope my opnion reach.
