/*
 * ace_parse_imagepath.cpp
 * Author: PabstMirror
 * Gets raw image path from structured text input.
 *
 * Takes:
 * Structured text that usualy has an image:
 * Example: "<img image='\A3\Ui_f\data\IGUI\Cfg\Actions\open_door_ca.paa' size='2.5' />";
 *
 * Returns:
 * Just the image path or "" if none
