Rack::SimpleUserAgent

Rack::SimpleUserAgent is Rack::Request extension which detects user-agent from request user-agent string. No complicated logic for the detection, it simply(stupidly) checks if user-agent includes particular string.

[ANNOUNCEMENT] Current request.from_smartphone? behavior is going to be changed in the next version. Please don't use request.from_smartphone?, use request.from_smartphone?, request.from_android? instead depending on the use case.
