Updated Linux installer for the retail Unreal Tournament version from http://www.liflg.org/ (Linux Installers for Linux Gamers).

Attention: Since the installer depends on the outdated and now obsolete GTK1 environment the following workaround should help getting it installed:

sh unreal.tournament_436-multilanguage.run --noexec --keep &&
cd unreal.tournament_436-multilanguage &&
./setup.data/bin/Linux/x86/setup
