Wrong generic type for deques in command README
Hi, inside the README.md for the command pattern the Wizard class presents these two instance variables:
```java
private final Deque<Command> undoStack = new LinkedList<>();
private final Deque<Command> redoStack = new LinkedList<>();
```

The generic type for these deques should be ```Runnable``` as it is in the Wizard class under src directory
