Parliament Contract

The production nodes use the Parliament contract to govern important matters. In the initial state, the production nodes are members of the parliament, and only when two-thirds of the production nodes vote in favor of a given decision, will it be executed.

Implement aelf Standards ACS1 and ACS3.
