Title: Add Allow header in HTTP Response

I create a new because issue #52 is also about relation links.

RESTful responses should include `Allow` header as stated in [rfc2616](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.7):

> The Allow entity-header field lists the set of methods supported
> by the resource identified by the Request-URI.

Note that I'm new to Symfony2 and the way I determine the available methods may not be the most elegant.
