Subject: config->site_url() optimizations

- direct access to config array, instead of item() calls
- the string cast is just in case 'url_suffix' would be set to false or null; the function produces the same results without this cast, but it leads to a robuster code, as false and null are sanitized and skip the suffix insertion code
- altered conditional structure: if no suffix, skip the appending of an empty string to $uri
