Univention Corporate Server 3.2 erratum 133 (bugfix)

This update fixes the following issues:
* Improved performance: Applications are opened immediately when clicking on
  them from the App Gallery.
* Improved performance: When new apps are added or existing apps' meta
  information changes, new files need to be downloaded from the server. If
  many files have changed, instead of downloading them all one after another,
  a compiled archive is downloaded and the files are extracted. This also
  fixes issues with many concurrent connections opened on the App Center
  server.
* A dedicated component for the Radius application is removed (if Radius is
  installed). It was added by mistake as univention-radius is part of the
  main repository.
* The UCR variable repository/app_center/installed is set and kept
  up-to-date. It reflects the state of the installation status of all apps.
* The details of an application do not show the note whether this application
  sends information to the vendor or not if it is a UCS component.
