log and log trie multicodec types (#223)

Add eth-receipt-logand eth-receipt-log-trie types

Also:
* Clarify ETH "block" terminology, as it is actually only the header that is hash referenced by "block" hash and the header in turn contains all the roots to the tx, rct, state (and thereby storage) tries.
* Changed "RLP" to MarshalBinary in the description for tx and rct, because after EIP-2718 tx envelopers were introduced the consensus encoding of a tx or rct is only the pure RLP encoding for the legacy types.
