Should allow server side 201 with one cute line of code

In order to support 201 on resource creation, Restfulie currently requires you to:

1) respond_with @order, :status => 201, :location => order_url(@order)
and create a create.tokamak file

2) render :text => "" , :status => 201, :location => order_url(@order)

(head 201, :location ...) is not an option because Rails seems to wrongly send a one whitespace string as a result.

Both should be easier implemented as something like the following, automatically noticing its a 201 and requires the Resource location, while rendering it with the resource itself (show.tokamak).

respond_with @order, :status => 201
