Gallery Shortcode Style to Head Plugin

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]
shortcode is used in any posts.

This plugin also gives you the option to modify the default gallery style
CSS or disable the gallery styles entirely (so you can control it from your
template CSS files).

This plugin uses ideas recommended in a patch located at
https://trac.wordpress.org/attachment/ticket/6380/6380-style.diff
