Hi,

Two updates on dynamic mappings. The first is that the format has change,  
and dynamic templates are now named. This allows for much simpler handling  
when merging mappings. The second is that dynamic templates can only be  
defined on the root level (object mapping) and apply to all inner object /  
field. This provides much better behavior when introducing a new template to  
a live system.
