Bug fixed: Messy codes when use string function "capitalize" on double-byte string

blueish模版，右边pannel中文title乱码

Bug: When we use blueish template, it showes pannel title on the right of the page. If we use local_zh_CN, the pannel titles are chinese. Capitalize these chinese words will make the sentence mess.

Fix: rewrite the capitalize function. see details below

file: class/template/smarty/plugins/modifier.capitalize.php

function smarty_modifier_capitalize($string)
{

    //-- return ucwords($string);
    $strarr = explode(" ", $string);
    $i = 0;
    while( $i < count($strarr) )
    {
        $w = $strarr[$i];
        if($w && Ord($w)<128)
                $strarr[$i] = ucfirst($w);
        $i++;
    }
    return implode(" ", $strarr);
}

Problems: capitalize is not a build-in function, but php4 does offer this function, it's realized with C codes. It uses toupper() to make the first char uppercase. toupper is locale sensitive function, when it deals with chinese string, the error occurs.

I'm absolutely PHP newbie. There must exist a much better way to resolve this problem, and, perhaps what I updated will bring other unknown new bugs.
