Removed AppState remnants.
Added knowledge of bounding volumes for placement of objects in the tank (including fish's random destination). But the bounds that jmonkeyengine returns are way too large. idk why. Added function (commented out by default) in ClickActionHandler to display a bounding box for each clicked object (the box is added to the object so it actually increases its bounding volume, so only click once). Plants and pots are still given hard coded 'buffer distances' from the bottom of the tank. Those distances will NOT work for plants/pots of different sizes...
