Banned BB Tags

There is an issue where the tag are case sensitive
If you ban [ QUOTE ] people can use [ Quote ] etc...

Here is the solution to make it case insensitive:
Replace

$vbulletin->GPC['ccb_newmessage'] = str_replace($cybcb_bannedtagsf, '', $vbulletin->GPC['ccb_newmessage']);

With

$vbulletin->GPC['ccb_newmessage'] = str_ireplace($cybcb_bannedtagsf, '', $vbulletin->GPC['ccb_newmessage']);

Look carefully they are different...
