Title: Update module/get.php to access settings/nxc_captcha.ini.append.php

Passing an attributeID '-1' ( /nxc_captcha/get/-1//(regen> ) will allow an image to be created using only the defaults.

This is useful for expanding the NXC Captcha usage beyond object
attributes and into a general captcha form validator.
