Display apps on unity launcher

If you have app and want to display it when search in unity launcher... you need to add an entry for it in `/usr/share/applications`

example:

/usr/share/applications$ cat idea.desktop
[Desktop Entry]
Version=13.1
Name=Intellj Idea
Exec=/home/mhewedy/disk/programs/idea-IC-135.480/bin/idea.sh
Icon=/home/mhewedy/disk/programs/idea-IC-135.480/bin/idea.png
Terminal=false
Type=Application
Actions=
Categories=Programming
Actions=Profile;Tray;
Keywords=idea;java;intellj;ide # keywords to search with to find the app, very important


That's all!
