Subject: [PATCH] Update include/admin/templates.inc.php

to avoid displaying older template vars in case of a template change like from BP to some other Template, in case of:
- previouses config_groups in templates with a config file and
- all other other core used vars in case of no config file
This may need further finetuning...
