[#170] Invoke all alphabet contracts for voting

Browse source 
Now alphabet contracts use signature collection to make
a vote. All inner ring nodes votes for some list of validators
the same way as they vote fore new epoch or new container.
As soon as list is accepted by alphabet contracts, each of them
votes for one candidate from the list.
