Noah Campbell f28a8fa0c2 RenderThing test cases
Provide unit test support RenderThing.

One observation is that creating the site.Tmpl variable is a one time
event.  site.Tmpl doesn't like additional templates with the same name.
This means that updating a template while in --watch mode requires
throwing away the entire Site object and creating a new one.  Not that
this is a bad idea, but it is something I discovered while working on
these unit tests.
