Mochimo 3.0 Suggestion - Add new OP code to retrieve block trailer & txids

[0rtis]

Add a new OP to retrieve a specific block trailer and all the txid of the block. This will permit wallets to verify through the mroot that a transaction has been included in the block without fetching the whole block

This idea is still on the radar, and currently planned for v3.1, with various other network protocol improvements. Some have made claim to this idea as if it were their own. I will not stand for such blasphemy. This issue will remain open until implemented as a testament.
