411ebdf51e cli: add complete support for offline signing, fix #2662 
See documentation update for an example. Some code is made generic as well,
GetCompleteTransaction can now be used directly on ParameterContext.

58707c2b1e context: handle the case when we have more sigs than needed 
We can technically have more signatures in the file than we need and it's OK,
this case should be handled.

efb67a0ea3 context: scripts and signatures are base64-encoded in C# now 
So use base64 too and add compatibility test. Unfortunately this breaks
support for old (hex-based) files, but those should be completed a long time
ago.

59b4377f90 context: support Neo.Network.P2P.Payloads.Transaction type 
C# now uses this one, so use it by default, but also accept old one.

dc980b5847 sc/context: add network magic into the context 
See neo-project/neo#2393, we need this to be able to sign multisig
transactions.

106c27782e cli/wallet: allow to cosign with a contract 
Contracts have empty verification script and their hash is
calculated differently.

db027ad9c5 vm: zero GAS means no GAS, use fee data to properly limit execution 
We were accepting transactions with zero system fee, but we shouldn't do
that. Also, transaction's verification execution has to be limited by network
fee.

b483c38593 block/transaction: add network magic into the hash 
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.

21efccd300 transaction: remove type field, set Version to 0 
Two changes being done here, because they require a lot of updates to
tests. Now we're back into version 0 and we only have one type of
transaction.

It also removes GetType and GetScript interops, both are obsolete in Neo 3.

941410a840 core: change verification scripts to new format

CHECKSIG/VERIFY opcodes.

9abda40171 testserdes: implement helpers for encode/decode routines 
Frequently one needs to check if struct serializes/deserializes
properly. This commit implements helpers for such cases including:
1. JSON
2. io.Serializable interface
