4395cea344 storage: fix reading overlapping hash blocks from the DB 
In the unlikely event of overlapping hash block written to the DB we might end
up with wrong hash list. That happened to me for some reason when synching
with the testnet leading to the following keys with respective values:
  150000 -> 2000 hashes
  152000 -> 2000 hashes
  153999 -> 2000 hashes

Reading it hashes number 153999 and 154000 got the same values and the chain
couldn't sync correctly.

d5d570f793 uint256: add Reverse(), change String() to be BE 
This one makes a little more obvious that we're operating with LE
representations mostly. Refs. #307. See #314 also.
