- Remove prompt for dialog4ports. Dialog4Ports is a

required part of ports 'make config' now. This is seen
  as not much different than any other dependency.
- Allow dialog4ports to work with INSTALL_AS_USER
  by building and using the port's WRKDIR version
  through a Tools/scripts wrapper
- Add NO_DIALOG for 'config' as well.
- Fix D4P environment variables not passing to dialog4ports:
  D4PHEIGHT, D4PWIDTH, D4PFULLSCREEN
