Title: Operator async

```contrib-async-util``` mostly renames, deprecated api removed, file comment fixed

Sidenote: for me, NetBeans 8.0 editor shows errors in all the files, unable to find rxjava-core classes. Using build command from the menu works. This is true for the other contrib packages as well. Any tips on why?
