Tile sheet (Tilemap Town)

A tile sheet is an Entity in Tilemap Town that holds a URL for an image file. A map tile or another entity can reference this entity in order to indirectly reference the URL stored on it. You can choose to create one when uploading a file, create one from an uploaded file, or just on its own.

The entity needs to continue to exist for tiles or entities to be able to reference it, whether it's in your inventory or somewhere else (see "nolocation" on Entity commands if you want to stash it somewhere that isn't in your inventory). If a tile or entity references a tile sheet that has been deleted, they will lose their appearance.

The purpose of this indirection is to allow you to update the appearance of all of the tiles you have placed when you update the image, and do so in one place instead of individually updating every single tile.
