wp-includes/vars.php still reeferences wp-images

[jaseone]

Line 106 still references wp-images when generating the smiley image tags, needs to be changed to:

wp_smiliesreplace[] = " <img src='" . get_settings('siteurl') . "/wp-includes/images/smilies/$img' alt='$smiley_masked' class='wp-smiley' /> ";
