Git should be able to record the file modes now.

They could contain local modification made by the admin,
so we will just create them when they are not present,
and leave them as they are if they are already on the machine.

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

Otherwise we would get something like this:

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

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

Users added:
-esamesync
-esame
-moodle
-rdesktop

Directory created:
-/opt/esame

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.

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