[mini-request] make smilies NOT case sensitive

[corsacrazy]

i swear i looked already and coulddt find it, however one simple search later reveals its already requested, sorry for your trouble

In admin/functions.php:

If you find:

$bbcode=str_replace(trim($smilie[smilietext]),"<img src=\"$smilie[smiliepath]\" border=\"0\" alt=\"\">",$bbcode);

and replace it as:

$bbcode=str_replace(strtolower(trim($smilie[smilietext])),"<img src=\"$smilie[smiliepath]\" border=\"0\" alt=\"\">",$bbcode);
$bbcode=str_replace(strtoupper(trim($smilie[smilietext])),"<img src=\"$smilie[smiliepath]\" border=\"0\" alt=\"\">",$bbcode);
