Comment 7 for bug 140005

This only fix the desktop and icon for ultrastar-ng-streamer but also installs the game data in /usr/share/ultrastar-ng/ instead of /usr/share/games/ultrastar-ng/ which was chosen by Debian.
The package ultrasta-ng-xine is not affected (its another rules target).
Also, if they are not used anymore, it makes sense to remove whatever .desktop and icons are in debian/.
In my opinion the best is to try to coordinate this with Debian, they may have other ideas as well (for instance patching Makefile.in or using some other icon than the one from upstream).
