Refactor field, refactor next shape drawing

Refactor field functions names. Transfer next shape drawing to painter.
Introduce idlist struct with foreach function. Refactor config.
Introduce color map array instead of "switch case" statement bloating
while coloring rectangles. Decouple field and shape structs from SFML
sfVector2 structs by introducing own vector2i and vector2ui structs.
Also remove sfRectangleShape members form field an shape structs.
