Wrapper dom changes in preparation for SVG

Wrapper dom changes in preparation for SVG

SVG defines methods that override base class methods. This requires
the Dart static helper methods to have unique names since Dart
inconveniently does not permit static method shadowing.  Rather than
furr up all the names with yet another copy of the class or interface
name, this change only adds the interface name if there actually is a
base class method of the same name.

Almost all of this change is due to applying the same technique to the
attribute getters and setters, which makes many names a little shorter.

Can you get duplicates from diamond inheritance?  Or, if the secondary parents
overlaps the primary above?
