Scaffolding your projects templates

[iainsimmons]

Adds the starting code for Stage 4: Scaffolding your Project's Templates in src/templates/index.jade and src/templates/post.jade so that Treehouse Students can follow along properly.

See forum posts about this issue:

• Hi, where can I find all the content inside the index.jade??
• Code described in Scaffolding Your Project’s Templates Video.

Apologies, I probably should have compared to the responseRenderMethod branch... This is my first pull request!
