Got output, default backwards

New page

--- This module is supposed to take all the normal File:/Image: parameters from the call
--- to a parent template (though it will might use its own args in preference for debug purposes)
--- and return them back one by one for use by a template. Most important, figure which is the caption.
--- (This is a bit experimental - I haven't really ''used'' the parent .args much,
--- and there's a chance the whole template will just get wrapped up into one Lua script in the end)
--- usage: {{#invoke Pseudo-image:main|thumb}}, etc.
