Add/Modify Package - hourly mail limits

For the root WHM user, when you add or edit a package the Maximum Hourly Email by Domain Relayed and Maximum percentage of failed or deferred messages a domain may send per hour values should default to the server-wide setting (maxemailsperhour and email_send_limits_defer_cutoff) instead of unlimited.

For non-root WHM users, the Maximum Hourly Email by Domain Relayed and Maximum percentage of failed or deferred messages a domain may send per hour values should be set to the server-wide settings (maxemailsperhour and email_send_limits_defer_cutoff) and not be changeable.

As it stands now (at least with cPanel 11.56.0.28) the root user can log in, edit a package, and inadvertently give that package unlimited email limits. Maximum Hourly Email by Domain Relayed and Maximum percentage of failed or deferred messages a domain may send per hour used to not be defined per package.
