Looking up custom fruitnames in the encyclopedia.

Looking up a custom fruitname in the encyclopedia will now yield
the encyclopedia entry for "fruit" if another matching database
entry is not found. This preserves the fun associated with naming
fruits after existing objects, while also preventing a failure to
find.
