#1 'render' template directive cannot be used recursively Templating Refactor and Cleanup defect normal 03/17/05

#2 Refactor Template Loading Templating Refactor and Cleanup defect normal 03/25/05

The Arrow::Template::load() functionality is duplicated in a quite a few places because nodes which load other templates (e.g., include, render) have to work around the fact that there's no real way to reuse a parser and its state while loading a subtemplate without doing it all yourself.

Solution: Refactor the stages of loading into reusable pieces.
