This version adds to the static typing changes in 0.11 and adds covariant/contravariant typing via super/extends generics.

Additional cleanup was done, particularly related to BlockingObservable. Also the window operator was added.

The largest breaking change is that Observable.create now accepts an OnSubscribeFunc rather than a Func1.

This means that instead of this:

public static <T> Observable<T> create(Func1<? super Observer<? super T>, ? extends Subscription> func)

it is now:

public static <T> Observable<T> create(OnSubscribeFunc<T> func)

This was done to simplify the usage of Observable.create which was already verbose but made far worse by the ? super generics.

For example, instead of writing this:

Observable.create(new Func1<Observer<? super SomeType>, Subscription>() {
   /// body here
}

it is now written as:

Observable.create(new OnSubscribeFunc<SomeType>() {
   /// body here
}
