Add new parameter to the GenericProposal (voting)

[AnthonyAkentiev]

Update the GenericProposal - https://github.com/Thetta/Thetta-DAO-Framework/blob/master/contracts/governance/GenericProposal.so

Old code

	function removeGroupMemberGeneric(bytes32[] _params) external {
		string memory _groupName = UtilsLib.bytes32ToString(_params[0]);
		address _a = address(_params[1]);
		removeGroupMember(_groupName, _a);
	}

New code

	function removeGroupMemberGeneric(IVoting _voting, bytes32[] _params) external {
                // use _voting here if you want

		string memory _groupName = UtilsLib.bytes32ToString(_params[0]);
		address _a = address(_params[1]);
		removeGroupMember(_groupName, _a);
	}
