Sign scriptPubKey using signature made with creator.

Signatures are returned in scriptSigRet (or returns false if scriptPubKey can't be signed), unless whichTypeRet is TX_SCRIPTHASH, in which case scriptSigRet is the redemption script. Returns false if scriptPubKey could not be completely satisfied.
