Exempt unspendable transaction outputs from dust checks #6444

1. 
   dexX7 commented at 8:15 pm on July 15, 2015: contributor

   Since unspendable outputs can’t be spent, there is no threshold at which it would be uneconomic to spend them.

   This primarily targets transaction outputs with OP_RETURN, and allows funding of data-only transactions with "fundrawtransaction".

   Pretty obvious fix, regardless of what we do with the IsDust() code in the future re: refactoring.

    We don’t actually have a coding style rule that says that.
