Unity Launcher Script

[itachi46]

Added a new script which allows user to select a file and create a launcher pre-filled and move it to usr/share/applications. This script was meant to be easier to use compared to the create-launcher script.

Thanks for your scripts. This script can be improved.

1. It can be copy to $HOME/.local/share/applications instead of /usr/share/applications, so user can avoid inputting password and put file to system folder.
2. Use "dconf read /desktop/unity/launcher/favorites" and "dconf write /desktop/unity/launcher/favorites "['x','y','z']"" to write into the launcher settings.
