Added the @Tag and @Tags functionality.

Hi Rob,

I wanted to use tags so I tried to add the functionality and you can now add a one or multiple tags to a controller or to the method itself. They will be added instead of overwritten if you add multiple.

Small example how to add them:
@tag(name="ControllerTag")
@controller
public class Controller {

@tag(name = "EndpointTag")
@get
public void get(Long id) {}

@tags({
@tag(name="tag 1", description="Tag 1"),
@tag(name="tag 2", description="Tag 2")
})
@post
public void post() {}
}

I must admin not sure if this is the correct way to implement it but it seems to work :)
