[Plugin: Custom Admin Branding] bad js inclusion, siteurl variable not initializated

there are two problems that prevent this plugin from working.

1. as pointed out in other messages in this thread, the variable that should contain the site url at row 169 of custom_admin_branding.php file is not correctly inizializated. instead of a variable, anyway, one should use the function site_url() like this:

<script type=”text/javascript” src=”<?php echo site_url(); ?>/wp-content/plugins/custom-admin-branding/js/ColorPicker.js”></script>

2. the thickbox.js jquery plugin seem to be not called at all.
