Univention Corporate Server 3.2 erratum 204 (bugfix)

This update fixes the following issues:
* Fixed suggestion of FQDN build from value entered in the organization field
  in appliance mode.
* Moved setup of apache startsite on EC2 to an earlier stage in the boot
  process.
* Do not show Firefox data submission policy popup during system setup.
* The Windows NETBIOS domain name can now be up to 15 characters long.
* Problems with reloading values and displaying messages after saving changes
  have been corrected.
* The UMC now warns the user if DHCP is selected but a link-local IP address
  is used.
  This can occur if DHCP is preconfigured but no DHCP lease could be obtained.
