Previously the Synchronizer required the initial variables of the smart
contracts to be passed as a configuration parameter (that the node took from
the configuration file).  The same applied to the blockNumber.

The last update of the smart contracts introduced events for each smart
contract constructor (initializer), which allows querying the initial variables
as well as the initial block number for each smart contract.

Now the synchronizer uses this information, and thus the initial variables and
the starting block numbers have been removed from the configuration.
