build errors on master

[yancyribbens]

Hi Kulpreet,

I'm encountering build errors that we discussed during the BTCR hackathon on master. When I run the install:

go get github.com/kulpreet/btcr-service

I get the following errors:

# github.com/kulpreet/btcr-service
src/github.com/kulpreet/btcr-service/decodeTxref.go:40:47: assignment mismatch: 6 variables but util.Decode returns 5 values
src/github.com/kulpreet/btcr-service/resolvetodid.go:54:41: assignment mismatch: 6 variables but util.Decode returns 5 values
src/github.com/kulpreet/btcr-service/tip.go:51:41: assignment mismatch: 6 variables but util.Decode returns 5 values
src/github.com/kulpreet/btcr-service/txref2txid.go:43:41: assignment mismatch: 6 variables but util.Decode returns 5 values

Thanks in advance for any advice you have.
