function _htmlpurifier_config_hack in HTML Purifier 7

Same name and namespace in other branches

1. 6.2 htmlpurifier.module \_htmlpurifier_config_hack()
2. 6 htmlpurifier.module \_htmlpurifier_config_hack()

Fills out the form state with extra post data originating from the HTML Purifier configuration form. This is an #after_build hook function.

@warning If someone ever gets the smart idea of changing the parameters to this function, I'm SOL! ;-) Also, this function does not work correctly if both filters from this module are enabled for the same format, since only one set of submitted values will make it through.
