Ed Sanders edcaaf9edc Use static.name once for ce and dm nodes
Add a static.name property to ce nodes and make sure both ce
and dm nodes always use the static.name property in constructors
and registration calls.

The result of this is that any given node type should now only
appear once in the code as a string.
