Command line with task generator and Enemy prototype

What's new:

 - Experience points that the player gets as he progresses through the game. 

- Command line, where the player receives information about what is happening around him. 

- Generator of tasks for the player. Now you don't just need to wander aimlessly around the planet, as you can complete tasks and get bonus experience points. 

- Enemy prototype. While this is a red cube, which, like you, collects garbage and will not refuse to spoil your health with close contact.
