Lukas 59bbeff1c1 Improve the block transfer logic 
- Fix a bug where the blockchain could not be synced completely when
  block transfers happened in parallel
- Sum up multiple received blocks in the log output

Lukas 0aa58b137b Fix a bug that prevented the blockchain to sync 
Blocks with reveal transactions that were loaded from disk could not be
distributed to other nodes before. This prevented new nodes with an old
blockchain state from synchronizing the blockchain.

This bug has now been fixed.

Lukas e1fe8b0958 Reorder field in the block 
Miners should choose a transaction from the network based on its reward,
not as part of the mining variability.
That's why it's a bad idea to place the transaction as last block element.

Reorder the fields to make less room for harmful mining optimization.
