Title: auto-detect and set the content type based on the template extname

This updates the sinatra runner's `render` method to detect and set
the content type based on the template name `extname`. This provides
a way to specify content type based on template naming conventions.

If the template name has no `extname`, `html` is assumed. Also,
any other metho of setting the content type will take precedence
over this so that custom content types not matching the convention
can still be used.

@jcredding ready for review. Closes #68.
