Title: Fix problem with Sinatra and Padrino

Hi,

after you change temple dependency now Sinatra is unable to set the `:outvar`
[see here](https://github.com/sinatra/sinatra/blob/master/lib/sinatra/base.rb#L697)

also Padrino has some problems but with `:buffer`.

I don't know what are Temple defaults, but any can be fine to prevent the error

```rb
Silm::Engine has not default options for :outvar
```
