Add types of functions

[FoksVHox]

Add:
protected
public
private

Just like in PHP ;)

that would be hard to implement in lua tho, maybe it can be done by simple adding a _ as a prefix for the names (so you know that you should not access it)

otherwise you may need some way to see where its called from and only return the stuff it the caller is for example in the table itself (which will reduce performance tho)

Adding Private and Protected in Lua is hard to enforce as you can always access the variables traversing the stack. This is something We might circle back to in the future.
