     * Parses a String, assumed to be a list, into a String array. Each item in the list must be
     * separated by a newline character. Space characters are ignored. The ignore list is case
     * sensitive, and only checks if each String in the list starts with the specified text; this is
     * useful for parsing out comments and/or unwanted crap.
     * 
     * @param s The String to use (must be delimited by new line chars)
     * @param prefix Adds a prefix to the beginning of each element. Specify "" for no prefix.
     * @param ignorelist If an item in the list contains a String in this list, it won't be included
     *           in the final result. Whatever you do, don't put an empty string in here; you'll be
     *           sorry :3
