support widgetsInTemplate (nested widgets in a template)

[bill]

Allow widget templates to have dojoType="..." which create widgets recursively. I guess this would be a mixin that extends TemplatedWidget?, maybe called TemplatedSuperWidget? :-)

Prerequisite for porting editor.

This was a 0.4 feature but has to be rewritten to work in dijit.

[liucougar]

the attached patch adds this feature to dijit.base.TemplatedWidget?, as there are only 10 lines in the code to handle widgetsInTemplate, so I did not make it into another mixin on top of TemplatedWidget?

now dijit.util.parser is always required in TemplatedWidget?. this is not ideal, need to find a way to load this optionally
