Timo Schilling e1fb3483d6 allow reseting of request variants
The current implementation of `variants=` don't allow a resetting to nil, wich is the default value.

This results in the following code smell:
```ruby
case request.user_agent
when /iPhone/
  request.variants = :phone
when /iPad/
  request.variants = :ipad
end
```

With the ability to reset variants to nil, it could be:
```ruby
request.variants = case request.user_agent
when /iPhone/
  :phone
when /iPad/
  :ipad
end
```

= Action Pack -- From request to response

Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.

It consists of several modules:

* Action Dispatch, which parses information about the web request, handles
  routing as defined by the user, and does advanced processing related to HTTP
  such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
  handling HTTP caching logic, cookies and sessions.

* Action Controller, which provides a base controller class that can be
  subclassed to implement filters and actions to handle requests. The result
  of an action is typically content generated from views.

With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.
