Check if $GLOBALS['TSFE'] is initialized #26

If the hook FormElementCaptchaHook is executed in the backend in preview mode, $GLOBALS['TSFE'] may not be initialized.

Also, it is no longer considered good practice to access $GLOBALS['TSFE'] directly, but an alternative is missing in this case.

Resolves: #25
