Subject: [PATCH] Added remove_ingredient to add_ingredient

When adding ingredients, it WILL crash the game if duplicate entries exist, under most circumstances.
The quick and dirty fix is to remove it before adding it, a more complicated check would involve looking for it and updating an existing entry instead.

I just added the remove_ingredient so that the function is at least usable.
