Title: add NSMutableArray.SubList features

Currently you cannot extract a sublist from a mutable array and add it to another collection:

```java
NSMutableArray array = …;
Collection collection = …;

SubList subList = array.subList(startIndex, endIndex);
collection.addAll(subList);
```

This patch adds that feature, corrects the value for count() and implements a useful toString method.
