....Adds effects for the following mineral floors: Plasma, Uranium, Bananium.

1. Bananium Effects:
1.A. Honking sound when attacking it/using your hand on it.
1.B. Squeeking sound when walking on it.

2. Plasma Effects:
2.A. Well, it burns when attacked by hot stuff or in a hot temperature.

3. Uranium Effects:
3.A. Mmm, it radiates people who walk on them. Strangely though for some reason it won't show the "Your clothes feels warm" message.

PS: IB4 @Miauw62 Yells at me for something.
Don't set numeric vars to null, please. It works in this case, but it's bad practice in general. Set it to 0 instead.
