Removed esame-get-config-boot.service as a requirement from some services (it is not needed anymore as esame-configurator target is reached before any other target at boot time).

That's where we run rsync for what's needed for the esame profiles.

Users added:
-esamesync
-esame
-moodle
-rdesktop

Directory created:
-/opt/esame

Fix: if the web service does not reply on machine boot, try 5 times then switch to graphical target.
If the WS does not reply when the machine is already in some exam mode or normal, do nothing.

Added warning and abort installation if the argument is 'v1.0' as the old installation procedure is different.

Removed creation of links for wanted services in esame and esamekiosk targets. They are not needed as targets already specify them in Wants directives.

FIX: stop action was empty, no reason not to resume kernel module instead (commands were commented).

The new installer will mainly be used by the anaconda kickstart,
so we cannot prompt a user/admin, as the installation is unattended.

there is no old esame.service to disable.
