Add CrmRegion Tag to Contact Actions menu template

We are working on a project that needs the Contact actions menu of the contact summary page to be modified. The template for the menu is here https://github.com/civicrm/civicrm-core/blob/master/templates/CRM/Contact/Page/Inline/Actions.tpl

Rather than override the core template,  The proposed solution is to add a  CrmRegion tag around the crm-contact-actions-list div tag so that custom content and markup can be injected.

Something like this: 

{crmRegion name="contact-page-inline-actions"}

  <div class="ac_results" id="crm-contact-actions-list">

  < existing html >

  </div>

{/crmRegion}

This proposed change will be useful incase anyone needs to add custom markup to this template too.
