What Am I Looking At

A simple spiritual port of What Am I Looking At? to StationAPI (Minecraft b1.7.3). The relevant code is literally one file.

Tooltips appear in the top-left corner when you look at something.

• Block tooltips show the name of the block you're looking at, as well as what it looks like in your inventory, its ID, and what tool you need to mine it.

• Entity tooltips show the name of the entity you're looking at, as well as its health (if applicable). Because of how beta Minecraft never bothered to set the max health of entities, all entities have 10 hearts of max HP (not my fault).
