Adding star-power

[BenjaminDeJager]

You will implement fire-bar related properties. You don't have to display this on the map, just create a structure/properties for this object. In other words, adding to levels that includes a star-power drop is not part of this issue. Please see the specific issue for that level.

1. Spawn inside in bricks or on their own depended on level layout
2. Bounce when hitting floor/wall
3. Mario should be able to pick up this
4. Give Mario an invulnerability period and insta-kill enemies that touch him
5. Sprite animation
