- Renderer figures out templates, contexts, and does a render call
- Templating is now handled with a single function
- Context call is made in the renderer
Note: to make this work, all controllers now define a little bit of config, currently stored in res._route. (That's a totally temporary location, as is res._template... when a sensible naming convention reveals itself I'll get rid of the weird _). This exposes a type and for custom routes a template name & default.
