Move default colours to a action hook

[dd32]

At present, wp_admin_css_color() is being called directly from wp-admin/admin.php this has the disadvantage, that if a plugin wants to hook and output a themed page to admin-post.php, its not possible to do that whilst retaining the colour themes. (As admin.php is only included for "content filled backend pages"

Attached patch moves it to a function thats hooked to admin_init.

Wouldn't it make sense to offer the hook (or another one) to actual be able to offer color-shemes by a plugin as well?

[dd32]

No. Not really. Theres the admin_init hook for initialising anything admin related, it suits fine.

I did think of adding a do_action('colours-init'); but didnt think it was really needed since it would become an alias for admin_init
