Add skills to Otto Starter

[IvanR3D]

On Otto Blockly it is possible to find some cool moves for biped versions of Otto, those moves are:
Moonwalk, crossing, flapping, swing, updown, tiptoeSwing, jitter, ascendingTurn.

We want to integrate them to the controller. Initially I have consider a dropdown menu that allow you to choose the move and then after clicking a "play" button Otto can execute the preselected move. (This idea is open to discussion)

This task can be split in two parts:

• Frontend part: add the design in the controller that allow to select the move.
• Backend part: add the Arduino code in the OttoS.ino file to execute the move.
