[BUGFIX] Directly resolve links to pages of type External URL

HMENU provides a way to directly create the external link
if a page is of type "External URLs" but typolink does not
resulting in

a) more bandwidth / hits for TYPO3 when using typolink
b) different results / expectations.

The patch makes typolink handle external URLs like HMENU.
