upsell message in all admin pages cannot be dismissed

This is a useful plugin, however having it add a advertisment on all admin pages which cannot be dismissed without editing the plugin file is not cool.

Please see section eleven of the Detailed Plugin Guidelines:

The admin message on all admin pages which cannot be dismissed does not comply with with the published guidelines. Please update the plugin so it is in compliance.
