move portal-gui django app to $top/rpkid/rpki/gui
change dashboard url to /rpki/ put myrpki cli path and confdir into settings.py rather than generating glue.py at build time don't use the old myrpki images on the dashboard no longer need to include the portal-gui python module in sys.path since it is installed in site-packages svn path=/buildtools/subst-vars.py; revision=3646
