Optimisied Blend Normal Node

Browse Source 
I've also added a getNormalZero to get a normal that has zeroed out, i.e. it faces directly outwards from the face. This enables the user to not have to input a vector for either the Base or Additional Normal inputs and still get a result that is acceptable. This is handy if you want to "wash out" a normal.
