[CQS] Some realistic ideas for doors and chests

DOOR OBSTRUCTED BY AN ENTITY
11. The door cannot be opened or closed if there is an entity in its block. Player will receive a warning that the door is obstructed

ANIMATION AT THE DOOR
12. Animation of the door opening and closing, just like the chest has its animation

CHEST DOES NOT OPEN WITH WEIGHT
13. Chests cannot be opened if there is a heavy entity on top of it. Light entities will be thrown backwards (if there are blocks behind, the entity will suffer damage due to impact) and when closing, the entity on top of the chest will be thrown forward (if there is a block ahead, the entity will suffer damage due to impact)
