Subject: use images from offical mirror

Do not generate images locally but instead generate signatures locally
and use images from offical mirror.

- generate ipxe boot script from template
- add option to start sshd with firstboot
- add version information when selecting branch
- verify netboot releases with gpg signature
- added ncopa.asc gpg public key
