Change how SMaterial handles equality for UserData for more flexibility

Browse Source 
Different UserData values are no longer by default causing materials to be different.
It now always checks in this case the IUserData != operator.
This allows more user control. Can still have them be different by checking pointers in overloaded compare function.
