InferenceGames: new level spec changes for levels 5 and 6. See issue #160 on github
Ship Odyssey: Resolved Issue #154. Implemented new Sea Wall mechanics, as per Cliff's Specification on Oct 9th.

1st treasure is either on the left or right wall. 2nd treasure is the oposite wall. 3rd treasure is in the middle. Then, an array with 2x left, 2x mid, 2x right is shuffled and sampled without replacement.
Removed semitransparent white background from results and justified the results text.
