Was broken both on the way in and on the way out.
* Move alien restoration (data->DOM) out of the main getDomFromData()
function and into getDomElementFromDataElement(). This means the
comment about District 9 is gone (sniff), but moving this here ensures
all code paths hit it (previously, it was assumed annotated nodes
could never be aliens).
* In the DOM->data converter, add annotation application to
getDataElementFromDomElement() (for content nodes) and createAlien()
(for aliens). Previously, these nodes would not get annotations.
** ve.AnnotationSet doesn't have a constructor that takes an array, we
should fix that.
