Log Message:
-----------
- new functions safeget, safepost, safeserver
  Action: get value from $_GET/$_POST/$_SERVER[$param], otherwise $default
  Call: $param = safeget('param')   # instead of $param = $_GET['param']   - or -
        $param = safeget('param', 'default')
  useful to avoid "undefined index" warnings ;-)
