Automatic running of promise handlers

[tecc]

Perhaps add an auto() method to promises, telling it that it should get the result and run all functions as soon as they're added.
Could work with some cleverness.

Example of automatic running of handlers

Promise<HttpResponse> promise = /* something */;
promise.auto()
    .then((response) -> {/* handle */})
    .exception((ex) -> {/* handle exceptions */})
    .conclude(() -> {/* and conclude handling */});
