Temperature readout of highest layer can get occluded by energy balance indicator

This problem is probably best told in pictures.

This was pointed out during today's design meeting. We decided that the best fix would be to move the indicator to the right when the energy balance indicator is active. @arouinfar said that this should not block the publication of the prototype for #220.

I've implemented a change that makes the temperature display move out of the way when the energy balance indicator is visible. @arouinfar - Please review and close if this looks good to you, or comment and assign back to me if not.

The design team, including @arouinfar , reviewed this in today's meeting and this has been approved. Closing.
