added temporary backend developer template dir switch - Please read:

The smartified code as forked from master to 2.0 being outsourced,
now is to find in /include/admin/tplold, which will still be used as
the default backend template dir.
To switch to the new version, please paste the dirs and files of s9y-admin-tpl
as adviced in the readme and reload, but also add a
```php
	// End of Serendipity configuration file
	// You can place your own special variables after here:

	define('SWITCH_TEMPLATE_VERSION', 'true');

```
to the end of your serendipity_config_local.inc.php.

To switch back to the old smartified files, just set a // to the define().
