move creation of website scripts to setup script

Instead of creating the website wrapper scripts with cmake,
they are now created when --setup-website is called. The
setup of the configuration constants is directly embedded
into the scripts. This means we can get rid of the separate
settings-frontend.php. More importantly however, it means
that it is now possible to set up multiple website directories
from the same build directory.
