Control codes are confusing the IRC prebot

[gkoh]

The nZEDbPRE channel appears to have started colourising and styling the IRC entries enough to confuse pynab's prebot. My prebot stopped processing any pres 5 days ago.

Looking through nZEDb's own IRC bot, I see a function call to _stripControlCharacters() which looks like this:

    /**
     * Strips control characters from a IRC message.
     *
     * @param string $text
     *
     * @return string
     *
     * @access protected
     */
    protected function _stripControlCharacters($text) {
        return preg_replace(
            array(
                '/(\x03(?:\d{1,2}(?:,\d{1,2})?)?)/',    // Color code
                '/\x02/',                               // Bold
                '/\x0F/',                               // Escaped
                '/\x16/',                               // Italic
                '/\x1F/',                               // Underline
                '/\x12/'                                // Device control 2
            ),
            '',
            $text
        );
    }

I believe the pynab IRC parser will need to do the same thing.

Aha, I was just looking into submitting my own fix for it, which is identical. Excellent!

This is a duplicate of #275.
