Moved webCheckTimer into viewDidAppear. This means that the tree and co2 data is updated as soon as the app is visible - previously it only fired after a fact was shown.
Added a simple go to Facebook link. These links are not modal and run the risk on losing the customer.
Changed constraints on tree page to have the tree take up less space if necessary (its scrolls after all).
Modified the Sun in the forest scene to be positioned relative to the edge of the screen.
Hard coded various colour levels on the forest view.
