ANother code path cleaned :)

OK, this was a bit more complex, mostly because I missed the support of multiple <configuration> elements within <pxedeploy>

All PXE*_legacy methods are gone.

I built the pxe example with the current version of kiwi and then built it with the new code. The config files for the PXE setup were identical. I did not try and deploy the images as I have no PXE infrastructure setup. Need to do that one day.

Enjoy,
Robert
