This adds a flag to define the default behavior for unhandled rejections. Three modes exist: `none`, `warn` and `strict`. The first is going to silence all unhandled rejection warnings. The second behaves identical to the current default with the excetion that no deprecation warning will be printed and the last is going to throw an error for each unhandled rejection, just as regular exceptions do. It is possible to intercept those with the `uncaughtException` hook as with all other exceptions as well. This PR has no influence on the existing `unhandledRejection` hook. If that is used, it will continue to function as before.
