Java: Include annotations in af and aF textobj

[flwyd]

When operating on a whole function it is likely that the user would like to include any annotations. JUnit is a common example:

@Test
public void testGreeter() {
  assertEquals(greeter.greet("world"), "Hello world!");
}

daf or dAF should delete the function and the @Test annotation rather than leaving the latter suddenly attached to the next method.
