Update to 0.3

A new system of positions
Previously, all objects and enemies appeared in pre-prescribed places, now there is a list of positions that are assigned to everything that is on the map. As an example, any enemy and any weapon can appear at position 17;15, not just a slime.

Say no more about epilepsy
Project has a main cycle of map printing -> enemy action -> enemy symbol printing -> player symbol printing -> player action. Previously, at the end of the cycle, the console was cleared. Now at the end of the cycle, the position for printing the map is moved to 0;0, to the beginning of the console.

Added 2 new maps. Slightly changed architecture, does not affect the experience from the project.
