Add wp-admin body classes for wp_version and admin_color
|Reported by:||andy||Owned by:||nacin|
Some plugins (e.g. WordPress.com Stats, Jetpack) display in their wp-admin pages sections of HTML generated remotely. As the styling of this HTML is affected by both WP version and the user's admin color scheme, these plugins need to modify their HTML to include CSS fixes dependent on those parameters. Rather than send the parameters for dynamic style generation, we should add body classes specifying the WP version and color scheme.
Attached patch adds body classes to wp-admin.
