Title: Automatic context accessors detect closures

This change affects the context class generated for rules like the following:

```antlr
x : y* ;
z : y+ ;
```

Previously the automatically generated `XContext.y()` and `ZContext.y()` each returned `YContext`. The closures are now properly detected and the methods return `List`.
