Issue on template copy

This plugin has an issue when check if template files was copied to child theme.

See above (index.php line 327):

$kbe_archive_file = KBE_THEME_DIR.KBE_FILE_DIR.'/archive-kbe_knowledgebase.php';
        $kbe_kbe_file = KBE_THEME_DIR.KBE_FILE_DIR.'/kbe_knowledgebase.php';
        $kbe_style_file = KBE_THEME_DIR.KBE_FILE_DIR.'/kbe_style.css';
        $kbe_single_file = KBE_THEME_DIR.KBE_FILE_DIR.'/single-kbe_knowledgebase.php';
        $kbe_taxonomy_file = KBE_THEME_DIR.KBE_FILE_DIR.'/taxonomy-kbe_taxonomy.php';
        $kbe_tags_file = KBE_THEME_DIR.KBE_FILE_DIR.'/taxonomy-kbe_tags.php';
        $kbe_comment_file = KBE_THEME_DIR.KBE_FILE_DIR.'/kbe_comments.php';
        $kbe_search_file = KBE_THEME_DIR.KBE_FILE_DIR.'/kbe_search.php';

        if((!file_exists($kbe_archive_file)) or (!file_exists($kbe_kbe_file))or
           (!file_exists($kbe_style_file)) or (!file_exists($kbe_single_file)) or
           (!file_exists($kbe_taxonomy_file)) or (!file_exists($kbe_tags_file)) or
           (!file_exists($kbe_comment_file)) or (!file_exists($kbe_search_file))) {

When checking for this file KBE_THEME_DIR.KBE_FILE_DIR.'/archive-kbe_knowledgebase.php, the plugin are checking for get_template_directory() . get_template_directory() . "/wp_knowledgebase/archive-kbe_knowledgebase.php" where the file never will exists. Then, on every page load all template files are overwriten.

To fix it, just change from KBE_THEME_DIR.KBE_FILE_DIR to KBE_FILE_DIR between lines 327 and 334.

Thanks!
