new op code additions
Created by: urban-idler
-- OP_REGISTER, OP_DEREGISTER and OP_META with functionality of OP_RETURN to store associative hashes/keys/message digests. -- Allow two data fields in a transaction to allow us of register or deregister with meta. -- Transactions proceeds are spendable and should be recycled into block rewards. -- additional parameters & typing of registration and deregistration and types of keys (title, license, identity, application, service, etc.) not set to allow experimentation in testnet. -- some other changes to remove darksend ui references in qt forms.
