fix for ipcop 1.4.15 RedMAC addon

RedMAC doesn't work with ipcop 1.4.15. After installing addons,
redmac package and rebooting, redmac still says it needs to reboot.
It is stuck. You can patch redmac.cgi with code below and change your
MAC right away and then reboot to get new red interface MAC setup.

This fix is for RedMAC-1.0-GUI-b1.tar.gz insert into /home/httpd/cgi-
bin/redmac.cgi right after line 44:
&Header::openpage($Lang::tr{'redmac'}, 1, '');
