Update trac header and footer for updated navigation link colors

[adamwoodnz]

See WordPress/wporg-mu-plugins#218

The link colors for the global navigation on wordpress.org sites were updated in WordPress/wporg-mu-plugins#214

This PR updates the trac headers to take these changes.

I ran https://github.com/WordPress/wordpress.org/blob/trunk/trac.wordpress.org/templates/update-headers.php to make the updates as suggested.

@adamwoodnz For sync things like this, you can just run the script and commit the diffs without needing to get a review, as long as you're not applying any customisations to it :)

Thanks, I struggled to find the update-headers.php script in my sandbox but I'll take another look

Ah, it doesn't exist, as not all files are checked out to sandboxes - you have to do a svn co https://meta.svn.wordpress.org/sites/trunk/trac.wordpress.org/templates/ and then run/commit it.

Because of that, I've just added bin/sync/trac-templates.sh just so we have all scripts in one place :)
