Due to the way dust is calculated, if the transaction relay fee is zero, then a zero output amount is not considered dust. As the transaction authoring code used this dust check to determine whether a change output can be included or not, it could create unnecessary change outputs which return no value back to the wallet. Prevent this by including an explicit check for zero values. Conflicts: wallet/txauthor/author.go wallet/txauthor/author_test.go
