Add support for @HttpParameter

[cescoffier]

Issue related to #204.

The @HttpParameter annotation is designed to ease the injection of HTTP related attributes in action methods. Lookup is made by the parameter's type and if ambiguous by a hint given as parameter:

• if the parameter's type is Context, the HTTP context is injected
• if the parameter's type is Request, the HTTP Request is injected
• otherwise, the value is looked up in the HTTP Headers, in that header value is converted to the parameter's type using the converter engine

Here is the resolution algorithm:

• if the parameter's type is {@link org.wisdom.api.http.Context}, the HTTP context is injected
• if the parameter's type is {@link org.wisdom.api.http.Request}, the HTTP Request is injected
• if the parameter's type is {@link org.wisdom.api.cookies.Cookie}, the Cookie corresponding to the argument's name is injected.
• if the parameter's type is {@link org.wisdom.api.cookies.SessionCookie}, the Session Cookie is injected.
• if the parameter's type is {@link org.wisdom.api.cookies.FlashCookie}, the Flash Cookie is injected.
• if the parameter's type is {@link org.wisdom.api.router.Route}, the route is injected.
• if the parameter's type is {@link java.io.Reader}, the reader on the request body is injected.
• otherwise, the value is looked up in the HTTP Headers, in that header value is converted to the parameter's type using the converter engine
