Forgot to add esame-get-config.timer to esameshow.target and the target itself in the install script.

New feature (fix for someone...): don't erase user's home if the computer crashes or reboots during the exam.
The user's home is erased (if required) only when the exam mode starts the first time.

Added esamesync-esame.service to graphical.target requirements, so the boot process stops if the master server is not reachable.

Otherwise we would get something like this:

  useradd: user 'rdesktop' already exists
  Error creating user rdesktop
  User rdesktop was created

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.
