Fix for setting value on a class object thats casted as an Any

[wickwirew]

I ran into an issue setting a value on an object that was casted as an Any. From what I can tell the problem was in the storage. The type of the instance was not being recognized as AnyClass even though it is. What is happening is once it is passed to storage<T> casted as an Any the method type(of:) no longer returns the correct type of the instance, it returns Any due to the generics. Would like to hear your input.

Not sure if this is the best way to fix it. Another solution would be to remove the generics but that may break other things. This is less invasive

Heres an example of the original issue. Without the Any it works

class TestClass {
    var value: Int = 0
}

var instance: Any = TestClass()
try? set(35, key: "value", for: &instance)
print((instance as! TestClass).value) // Prints 0

@bradhilton any chance this can be reviewed and merged?

By the way, I believe this should fix https://github.com/Zewo/Zewo/issues/237 and possibly https://github.com/Zewo/Zewo/issues/238.
