Small fix to admin CSS

Hi,

Not sure about this one – Just a small cosmetic issue in the admin…

When editing pages I noticed 404’s in firebug trying to load wp-content/plugins/custom-post-widget/images/contentblock.png one directory below my wordpress installation root. Fixed by changing ../../ to just ../ in the css at the top of add_content_block_icon() in post-widget.php.

It may be because the relative location starting point differs in other browsers (I’m using firefox.)

(Many thanks for this very useful plugin.)
