Add Fire, Rotation. Document Health, Hunger, Position, Velocity, Level, Solid

components-system branch: Big thanks to @Zidane for starting components up
Documented some values with "value in {link org.spongepowered.api.math.Vector3i Vector3i}" due to the fact that new people may not be used to using Vector3i
The only reason I did interfaces for the mobs is we still haven't solved the issue of "Is My Entity an Enderman"?

If we put a marker interface that duals as providing the client the render id...that "fixes" it. Open to ideas...

(An enum is not an acceptable solution, period).
