killing is now done based on groups, the same way enemies already killed
the player.

these groups go on the entity's hitbox, not the entity itself.
enemies' hitboxes have all been put in "enemy_hitbox"

the arrow_projectile has a variable for the target group, so it could
easily be simply set to "player" for arrows shot by enemies

blocking is also done with groups. any hitbox with "blocks_arrow"
will block arrows, same with "blocks_sword" and "blocks_squash"

### IMPORTANT: enemy's hitbox must be in the group "enemy_hitbox" to be killed
### it should also be named "Hitbox" for easier (2 click) signal connection
### as the reciever function has been renamed with that in mind
