template_c directory not created or not pointing to the right place.

[Christopher C. Petro]

When installing postfixadmin from scratch you get an error:

ERROR: the templates_c directory doesn't exist or isn't writeable for the webserver

This is because there's a bug in smarty.inc.php:

        // if it's not present or writeable, smarty should just not cache.
        $templates_c = dirname(__FILE__) . '/../templates_c';
        if (is_dir($templates_c) && is_writeable($templates_c)) {
  <...>
          die("ERROR: the templates_c directory doesn't exist or isn't writeable for the webserver");
        }

Where the location of templates_c is (a) hard-coded and (b) hard-coded to a questionable (and relative) location.

The manual fix for this is to create the directory and chown it to www-data:www-data.
