Feature request - Opt out option for templating engine

[ghost]

Would be nice to have the option to just use standard HTML instead of having to choose Jade or EJS or anything. Planning on just serving an SPA via angular templates anyway and would prefer without another layer of abstraction/build step.

@petecoop This would be beneficial for those who do most of their templating via Angular or React (among others). A simple static HTML setting would make good sense as well.
