Add theme update counter in admin theme menu item

Add theme update counter in admin theme menu item as we show for plugin menu item.

Why does your code use the update-plugins capability and class name?

This used to work. Can you look back at older versions for that code?

@joyously I think using update-plugins as class name is not very intuitive, but at the moment correct.

The network menu is using it too:

We could either use it here too or add the class name to the CSS, because at the moment it does not exist:

@mukesh27 Looking at the patch and the screenshot it shows an inconsistent behavior: The badge is added to the first submenu item instead of the main menu item ("Appearance"), like it is seen for the "Plugins" menu item.

I would vote for using the same design as for Plugins (which is also used in a multisite):

Updated patch. Count is added to "appearance" now and is using the correct class names and caps.

I am still experiencing a strange behavior. There is a paid theme in my test environment with available update, but the notice "Automatic update is unavailable for this theme."

After leaving the themes.php page the count is changing from 7 to 6. On all admin pages it stays on 6. Just on update-core.php it is showing 7 again.
