Environment Functionality Added

File option Care/Clean & Care/Feed added and fully functional
 - Changed background default to wide and image changes as aquarium gets dirty
 - Timer starts when first fish added to check if they need to be fed.
 - If not fed after a set amount of time, all fish are removed from mItems
 - Only checks for items of type CFish to be removed (CItem types are ignored and left on screen)
 - Fix for fish, extend display to see (we will add scrolling later to fix this).

Future Improvements (optional)
 - Dirty levels effect fish
 - Some display/warning for needing to be fed (happens suddenly if not focused on time)
