Stacked sprite visualizer (#3096)

* Add Stack Visualizer

* Add cigarette pack resources

Adds transparent layers for visualizing cigarettes

* Add Bag Open/Close Visualizer

So storage opened in inventory can have different icons when opened
or closed.

* Create a component that only enumerates single item

Used for creating stuff like matchbox, or cigarettes. As a bonus.
It will only update stack visualizer for that particullar item.

* Refactoring stuff

* Fix other usage of stack in Resources

* Add docs

* Apply suggestions from code review
