[development] resetting a form

[Si Hobbs]

Part of my problem is not being able to define my own "delivery
callback" in hook_menu because my form is in a block.

If I cannot have my own "delivery callback", I'm struggling to work
out how to return my own series of ajax_comment_X() in my
ajax_callback. I can only seem to return a renderable array, or some
static content.
