Some System Workflow templates still miss {contact.email_greeting}

Not really a bug, but since there has been an agreement to use

{contact.email_greeting}

, some templates are not in agreement to that leading to confusion and despair. So sad.

Some of the templates I found that need to be changed are:

• Additional Payment Receipt or Refund Notification

• Contributions - Recurring Billing Updates
• Contributions - Recurring Cancellation Notification
• Contributions - Recurring Start and End Notification
• Contributions - Recurring Updates
• Contributions - Receipt (on-line) (missing greeting)

• Events - Registration Confirmation Invite
• Events - Registration Cancellation Notice
• Events - Receipt only
• Events - Pending Registration Expiration Notice

• Memberships - Auto-renew Billing Updates
• Memberships - Auto-renew Cancellation Notification (missing greeting)

• Personal Campaign Pages - Owner Notification (missing greeting)
• Personal Campaign Pages - Supporter Welcome

• Petition - need verification (missing greeting)
• Petition - signature added (missing greeting)

• Pledges - Acknowledgement
• Pledges - Payment Reminder

• Volunteer - Registration (on-line)

Actually the only ones that already have it are:

• event_offline_receipt_html.tpl:24
• event_offline_receipt_text.tpl:1
• event_online_receipt_html.tpl:28
• event_online_receipt_text.tpl:1
• sample/Sample Responsive Design Newsletter

Some have: <p>

{ts 1=$contact.display_name}

Dear %1

{/ts}

,</p>
Some have: <p>Dear

{contact.display_name}

,</p>
Some have event: <p>Dear {$contactDisplayName}</p>
Some have missing greetings

Since these are not files but live in the database I'm not sure what kind of patch is needed for this, being a result of my novice development skills
If someone would show me how to create upgrade files for this, I'm willing to attempt to create a PR.

I hope I helped the community by identifying this and hopefully we can make CiviCRM more consistent.
