Improve ECS singleton syntax #60

If you need to read the entity Component, or a Databag, from a standard GDScript function, it's possible to use the ECS singleton in this way:

func _ready():
    var component = ECS.get_active_world().get_entity_component(get_entity_id(), ECS.TransformComponent)

The function get_active_world is used to get the currently active world, however, this function is really verbose. Is it possible to make it shorter?

The function get_entity_component is good, but still verbose. Is it possible to make this shorter?

What about this?
Is still understandable?
Worth it?

func _ready():
    var component = ECS.get_world().get_component(get_entity_id(), ECS.TransformComponent)
