The util methods are now attributes on the TemplateUtils object (via
setattr(..)).
The __getattr__() method was removed as I set the method/staticmethod
directly
on the object.

So we shouldn't have leakage of methods between trackers when running
under roundup-server.
I don't know of any cases where that happened.
