Fix failing bench/checkblock.cpp benchmark test (#722)

[dsaveliev]

Fixes #722.

The test bench/checkblock.cpp is failing due to outdated block fixture.
Here are a few changes that have affected the block structure:

• add block signature #114 introduced a signature at the end of the block
• Change tx.nVersion to uint, add setter for type #44 introduced TxType
• UIP-0024 Implementation (CTOR/LTOR) #440 introduced LTOR

In order to fix it, I generated a new, synthetic block fixture.

Thanks for the fix. However, we'll need to open a new issue anyway, to replace the synthetic block with a real one -- a small block doesn't really stress the Unit-e daemon, which is the purpose of the benchmark.

Why not create a block with 1500 transactions for this right now, just like the original block 413567?

[dsaveliev]

@cmihai good point, I've increased block size up to 1500 transactions
