All ballots and voting methods are gone. Multi signature
checks are used in all contracts.
Default global config values are also removed. Configuration
must be provided by initialization script.

Ballots are inefficient to collect invocations of contract methods.
Instead contract can check multi signature collected outside of the
contract, e.g. with notary service.

Unified format uses transfer type as the first byte
and extra details next. List of transfer types used in
contracts defined in `transfer.go`. It includes:
- mint,
- burn,
- lock,
- unlock,
- container fee.

Even though it is allowed to do so, it can produce
invalid search results if key is less than 10 bytes.

`x*2/3` is not equal to `x/3*2` with integers.
The only correct way to calculate threshold is
the first one.

Proxy contract used by notary contract as a main tx
payment provider. `Verify` function verifies if
main tx contains multisig of 5\7 inner ring
nodes. If so, then contract pays for transaction.
This is easier than support multisig wallet with
GAS assets, because inner ring can change, therefore
multisig wallet can change periodically.

This check was useful when there was a single
entry point in contract. But right now there is
no point in this.
