3f6104ef4d network: ignore consensus messages
It's a temporary stub until proper encoding/decoding is implemented. It's
useful for testnet/mainnet connections because without it consensus message
receival leads to peer disconnection.

56459c6c63 network: remove port check from handleVersionCmd()
It's bogus and no other node implementation has anything like that. It fires
up for no good reason in the case when some other node connects to us and it
obviously doesn't use its listening port for it.

Merge pull request #425 from nspcc-dev/memcached-layer

a6610ba082 core: verify blocks, fix #12
This adds the following verifications:
 * merkleroot check
 * index check
 * timestamp check
 * witnesses verification

VerifyWitnesses is also renamed to verifyTxWitnesses here to not confuse it
with verifyBlockWitnesse and to hide it from external access (no users at the
moment).

03c20f1876 core: make ContractState receiver names consistent
Linter isn't happy with our recent changes:

pkg/core/contract_state.go:109:1: receiver name cs should be consistent with previous receiver name a for ContractState
pkg/core/contract_state.go:114:1: receiver name cs should be consistent with previous receiver name a for ContractState
pkg/core/contract_state.go:119:1: receiver name cs should be consistent with previous receiver name a for ContractState

But actually `a` here most probably is a copy-paste from AssetState methods,
so fit the old code to match the new one.

258f397b9a core: append transactions to the block in GetBlock()
We want to get a full block, so it has to have transactions

completely bogus transactions without data that couldn't be persisted, so fix
that also.

238c590ddb core: fix contract state's Properties to use PropertyState
PublishTX only had one of these flags, but newer contracts (created via the
interop function) can have more and these flags are aggregated into one field
that uses PropertyState enumeration (it's used to publish contract, so
supposedly it's also a nice choice for contract state storage).
