Ship Odyssey: DG error trace statements replaced with real Errors, to help us debug. Fixed issue where ending the game with rats animating caused several DG errors.
Ship Odyssey: Refactoring, removing obsolete variables. TreasureNamePicker is now a singleton static class.
Ship Odyssey: Fixed close game bug. Increased readability of several functions within PopUpScroll.
Ship Odyssey: Mission 'Treasure or Not' now uses a pseduo-random shuffle to determine how many treasures are found at each site.

First site is always 2.
Second and Third sites will have either 0 or 1. Both results will be seen.
The next three sites will have either 0, 1 or 2 treasures. All three results will be seen.
After that point, the number is truely random.

Ship Odyssey: Fixed "Info Button" bug, where it was enabled when not intended. Refactoring. Removed unused variables and functions, made "New Game" function clearer.
Removed 'onClickExitNewGame', all calls to it are now 'zoomOutAndSail'
Ship Odyssey: Cleaned up Treasure code. An array called treasureArray now handles most of the logic.
initTreasureHunt() folded into newSite().
Ship Odyssey: Renamed 'treasureArray' to 'mTreasureArray' for consistency. Removed unused constants.
Ship Odyssey: Fixed bug in Treasure or Not. Clicking Drop Hook now disables all buttons,
Previously, if you managed to click 'next Site' while the crane was animating to a drop, the game will lock up. This fix has the issue that should the crane & stepper become un-sync'd, the game will lock up.
Ship Odyssey: Delete previous games data box now remembers if it was checked.
made it so if sound is already fading in/out, fade functions return instead of doing anything. solves issue #123, but opens issue #118 back up. also added ifs to make sure sounds don't get faded out unless they are actually playing in AdvancedSound
