Janitor trashbag upgrade + FANCY ANIMATIONS (#3058)

* Janitor trashbag upgrade + FANCY ANIMATIONS

* Review, Bug fixes and Sounds
- Fixed hand-pickup animation playing if the entity originated from inside a container (e.g. bag on the ground) or from inside ourselves (e.g. something in our own inventory)

* Fix/Change. Just log if AnimateEntityPickup is called with an entity that has no SpriteComponent.

* More explicit log message. Error log.

* Merge. Fix.
