Suggestion: Discrete strafing actions

[salaniz]

There is currently no direct way of moving sideways using the discrete actions. The action set [movenorth, moveeast, movesouth, movewest] seems unnatural from the agent's point of view.

My current implementation looks at the current yaw of the agent and then uses the corresponding action from the above set that gives me move left or move right.
I used the information provided in the Minecraft Wiki to associate yaw with north/south/east/west.

I think it would be a nice addition to have a strafe left/right natively in the discrete action set.

Edit:
This information about orientation and yaw is needed:
Yaw - > Direction it points to:
0 -> South
90 -> West
180 -> North
270 -> East

Let's remember to include this into #301.

Fixed in #390
"strafe 1" -> sidestep to the right.
"strafe -1" ->sidestep to the left.
