Proposal - Extension tpls should support the tpl override feature, as supported by CiviCRM core tpls
Current feature:
Currently, an Extension can ship with tpls but these cannot be overridden which is contrary to the method of overriding CiviCRM core tpls using the custom templates directory.
Proposed change:
Extension tpls should support the tpl override feature, as supported by CiviCRM core tpls. So a developer can customise an Extension tpl on a per site basis by adding the tpl file to the correct location in the custom templates directory.
