[织梦建站]织梦版权去除powered by dedecms

织梦官方5.7版本升级后，版权标签{dede:global name='cfg_powerby'/}调用出来后会出现：“powered by dedecms”。

虽说开源程序应该保护一下版权，但是织梦CMS已经好久没有更新过了，一些不法之徒一眼看到你的网站是织梦，只会便于他们入侵。

所以无言决定去除这个版权显示。

在/include/dedesql.class.php文件中找到第588行：

$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79);
$arrs2 =array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f,
  0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72,
  0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20,
  0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e);

改成：

$arrs1=array();
$arrs2=array();
