add hidden objects

Adding hidden objects was actually easier than i thought.It was easier than i thought because in wiki it shows you how to do it step by step.Probably the hardest thing i had to do was probably to put the code for every tool and i'm saying it was hard because i drew like 15 different tools but i pulled through the boredom of doing the code.In conclusion it wasn't the funnest thing in the world to put the code in my game but i'm glad i did it.
