function _wysiwyg_delivery_dummy in Wysiwyg 7.2

A simple page delivery dummy implementation.

Renders a dummy string on a page so a pre_render callback on the style tag can collect all stylesheets, then grabs them from the cache and prints import rules for each file in the cache.

Success:

• Status header: "200 OK"
• Content: One import rule per stylesheet from the theme.

Failure:

• Status header: "403 Forbidden"
• Content: Empty
