Changed identity format in transactions, now it will be double Sha256.

Added new checks for forked blocks.
Added options table.
Added posibility to replace blocks in DB by more appropriate forks.
Divided transactions table to domains and zones tables.
Added a timestamp to domains and zones table, it will give us possibility to purge old domains.
Changed difficulty check to check head and tail (sum of them) of the hash.
Added encrypted (by Chacha20) domain name to DomainData, added contacts and owners vectors for it too.
Added yggdrasil flag to ZoneData - it will restrict all IPs for domains in particular zone to Yggdrasil only.
Changed difficulties of various block types.
Added a temporary (for a run) unique ID to all handshakes.
