Attack merge attempt 3.1

[qwet1235]

added EnemyConstants and PlayerConstants classes to make it easier to identitfy enemy/player states

[qwet1235]

notes:

• need to rescale hitbox
• add attack boxes
• implement movement + attack into each monster's class

[qwet1235]

• Added an EnemyManager class that keeps track of all enemies on the game. Need to update with methods for spawning
• Added hitboxes and attackboxes for all entities. The attacking methods should work but still needs a few tweaks. The game wont run properly cause we still need animations and need to add some other methods besides attacking
• no clean architecture
