Description

Currently org.apache.wicket.request.resource.AbstractResource#setResponseHeaders() flushes the response after setting the headers.
Matej added this with revision da1077e12e690fda9a7f47a745308a156df738bd because:
This is necessary for Firefox if this resource is an image, otherwise it messes up other images on page.

In some cases this flush causes troubles because it doesn't allow to reset the response in #onWriteCallback().
It will be better if the flushing is configurable.
