whitepaper functionality is broken with spectrum

getrawtransaction is not implemented in spectrum. Therefore the whitepaper functionality is broken.
#2056 tries to fix it by deactivating but that would be a pity, no?!

So waiting on cryptoadvance/spectrum#33

I have a PR up for it cryptoadvance/spectrum#39
Can you take a look at it? I feel it's really close
