ENHANCEMENT: Added the pmpro_approvals_member_approved_email_template and pmpro_approvals_member_denied_email_template filters.

These be used in conjunction with the pmproet_templates filter to create new templates in the PMP email templates screen and dynamically apply them to emails depending on - for example - the user level.

Hi @joeczucha

Thanks for contributing to the Paid Memberships Pro ecosystem.

It may be possible to use the pmpro_email_filter available in the core class to adjust any email right before sending - https://github.com/strangerstudios/paid-memberships-pro/blob/dev/classes/class.pmproemail.php#L208

I'm not sure if you tried this filter already, but do you have more information about these new filters and the need for them? It should be possible using the above filter mentioned but may require some work to get membership information.

Would love to hear from you. Thanks again!
