Added some types of Fruit. Code alignment fix.

We now have some subtypes of the Fruit Class, namely Apples, Oranges,
Grapes, Lemons, and Watermelons. These will be the five in game fruits.
Also tried fixing some alignment issues in Fruit.java for the constants.
This may or may not break on GitHub. :/
