init support for some reward handlers

[EHAT32]

I am currently trying to implement reward handlers (RewardForSendingCommand and RewardForTouchingBlockType). I have stumbled upon a problem when rewards should be triggered on the same tick when agent quits the mission. For example, i am running cliff_walking example. Missions ends when agent touches the lava. Thus, mission ends but no reward for sending a command is triggered. The same thing with RewardForTouchingBlockType, at first agent touches the lava, mission ends and no reward for touching lava is triggered.
For the first implementation i uncommented this code in ClientStateMachine.MissionRunningEpisode.sendData() and modified getReward() a bit:

// Now create the reward signal:
if (currentMissionBehaviour() != null && currentMissionBehaviour().rewardProducer != null && cac != null)
            {
                MultidimensionalReward reward = new MultidimensionalReward();
                currentMissionBehaviour().rewardProducer.getReward(reward);
                if (!reward.isEmpty())
                {
                    String strReward = reward.getAsSimpleString();
//                    Minecraft.getMinecraft().mcProfiler.startSection("malmoSendTCPReward");

//                    ScoreHelper.logReward(strReward);

                    if (AddressHelper.getMissionControlPort() == 0) {
                        // MalmoEnvServer - reward
//                        if (envServer != null) {
//                            envServer.addRewards(reward.getRewardTotal());
//                        }

Also, i noticed there's a code for getting rewards with a message of ended mission

private void sendMissionEnded(MissionEnded missionEnded)
        {
            // Send a MissionEnded message to the agent to inform it that the mission has ended.
            // Create a string XML representation:
            String missionEndedString = null;
            try
            {
                missionEndedString = SchemaHelper.serialiseObject(missionEnded, MissionEnded.class);
                
                if (ScoreHelper.isScoring()) {
                    Reward reward = missionEnded.getReward();
                    if (reward == null) {
                        reward = new Reward();
                    }
                    ScoreHelper.logMissionEndRewards(reward);
                }
            }

I tried to uncomment it as well but at first glance it did nothing. Perhaps, MissionEnded class should be modified or re-implemented? If i got it right, it is a class from Malmo and needs some modifications to work with Vereya.

I would like to get some advices @CICS-Oleg @noskill

After some further inspection i figured the problem might be in Python parsing MissionEndedXML and not in MissionEnded part in Java

In test_agent agent gets stuck looking down
