Don't send emails to disabled users.

This plugin addresses issue #5.

In the process, I also created a generic is_user_disabled() function that checks the usermeta value. This was being done in two places already, and this PR added a third.

Will this work if you replace Wordpress notifications with another plugin such as Better Notifications for WordPress?

@ebauch I just looked at Better Notifications for WordPress' code quickly, and I believe it is compatible. However, you should look at pull request 15 (#15 (comment)) instead. It's the better version.

@shawnhooper thanks for your quick response and support. I can confirm that this does not work with Better Notifications atm. It may be related to being a MU site. I deactivated users as Network Admin and they do show up as disabled in all sub-wordpress blogs. However, notifications are still being sent to all users. It may also be related of me using Post SMTP plugin and not the Wordpress mailer.
So it either doesn't work because of Better Notifications plugin, MU site, or the Post SMTP plugin.
Because #15 is not approved, not sure what to do next.
