 * run().
 * Note also that the templates are expected to end in ".tpl", worm will attempt to
 * identify the type of template according to the filename.
 *
 * On failure this sets a message in the database object and returns false.
 *
 * \retval bool - true if templates and metadata successfully initialized.
