81d89cd502 core: fix SystemFee calculation for Invocation TXes 
They have it specified right in the transaction. Unfortunately, this little
change rendered invalid our RPC test chain, but I think it became even better
after it, especially given that chain generation is a nice test by itself, so
it should be running as a regular test.

ae6edf0601 core: add a check for fractional gas in invocation TXes 
It's not allowed in C# code and that's reasonable as it's a sysfee essentially
that can only be integer.

c3e73c5b7d core: don't reverify stale headers in addHeader 
During networked synchronization we expect there to be a lot of duplicate
headers received and it makes no sense for us reverifying them.

6add4f3e50 transaction: disallow negative outputs 
Otherwise it is possible to make outputs which will sum
to the expected value, but steal GAS from some other account.

9e9d59b49a core: set NetworkFee to 0 for Claim and Miner transactions 
Claim tx have no GAS inputs and a positive output which
can lead to negative network fee.

1b9968df67 core: optimize CalculateClaimable()

72d72296c3 core: implement (*Transaction).GetSignedPart() 
Marshalling it and taking all but last byte violates incapsulation
and is just wrong in case transaction already contains any witnesses.

Refactor HaveInputsDuplicate() out of the core and Blockchain, it doesn't

9b1ad40273 core: drop GetScriptHashesForVerifyingClaim, fix Claim's ScriptHash getter 
Claim transactions should _add_ claims scripthashes to the standard list, not
replace them. And this code is actually very reusable.

c258adb532 core: move spent coin management out of the inner storeBlock loop 
prevHash == input.PrevHash, so make less DB accesses and more real work. Fix
some bugs along the way:
 * spentCoins structure may already be present in the DB when persisting TX,
   there is nothing wrong with that and we shouldn't overwrite it
 * it's only used for NEO and only to check for claim validity. Thus, when
   processing claim tx the corresponding spentCoins should always be present
   in the DB

36c6b6af14 core: put unspents get/put one loop above in storeBlock 
Everywhere in this code prevHash == input.PrevHash, thus we can easily move
some common code out of the loop saving on DB accesses and
serialization/deserialization.
