Don't hard-code hitbox for loot. Use tile size instead
Add option to toggle dispaly of the targeting animation
Add option to toggle display of loot labels

Similar to how Diablo did it. The default is 'on' (current behavior).
Turning it off hides all loot labels, except for those that are hovered
by the mouse. Pressing ALT will also temporarily display loot labels if
they are disabled.
