Add equivalent of JAXB @XmlRootElement to specify name of root XML element

(note: re-creation of [http://jira.codehaus.org/browse/JACKSON-452] by Chris Winters)

JAXB allows you to override the name of the root element (using @XmlRootElement when generating XML. For example, rendering this class to XML:

@JsonIgnoreProperties( {"meal", "notMeal", "mealNameDisplay"} )
public class MealEvent...

Generates XML like this:

lunch ...

But I'd like the root element to be 'meal' instead of 'MealEvent'.

FWIW, I tried the wild guess using @JsonTypeName( "meal" ) as well – it had no effect.

In this discussion Tatu suggested the annotation @JacksonXmlRootName.

Implemented: now there is @JacksonXmlRootElement (named similar to JAXB annotation, just with "Jackson" prefix to reduce confusion).
