Title: Rack params have string keys not symbols

Tried to use parameters in query string with Grape and found out that query string params that got passed to warden strategy are stored with string key not with symbol key. I believe, keys will be symbols only if you're running inside Rails and rails wraps params into HashWithIndifferentAccess. Anyway string keys should be supported by both Rails and plain Rack stacks.
