I've upgraded the Node version from 6 to 9 in the .travis.yml file due to the install-purescript-cli package using the spread operator (apparently not available in version 6).

That just leaves this UnusedTypeVar warning that doesn't entirely make sense to me since no e variable is used here... @paf31 maybe you can shed some light on this?

[1/1 UnusedTypeVar] src/QuickServe.purs:198:1
       v
  198  instance servableRequestBody
  199      :: (IsRequest request, Servable service)
  200      => Servable (RequestBody request -> service) where
                                                      ^
  
  Type variable e is ambiguous, since it is unused in the polymorphic type which introduces it.

Thanks @Thimoteus for helping me spot that unused type variable!
