Moves the gallery shortcode styles to the head so it doesn’t break XHTML 
validation; allows disabling or modifying the default gallery styles.
By default when using the WordPress gallery, the styles are placed into the 
post content which breaks XHTML validation. This plugin moves the style into 
the head of the page using a look-ahead to determine if the [gallery]
