authorURI defaults to /wp-admin/themes.php if not set in theme header

[morganestes]

If a theme doesn't include the Author URI field in the file header, it is still hyperlinked in the theme info modal window, but with an empty href.

Tested on trunk after THX38 integrated. I don't know what version this started with.

This only affects themes distributed outside the WordPress.org Themes Directory, as it checks for the proper file header.

My suggested fix is to check if the data.authorURI is present before creating the link. If not, display the author without the link.
