Fix Ninjhax output name and icon usage

It's better to give an output name instead of using the name of the current directory, so 'ftbrony' is used as default. I also fixed the icon not being used in SMDH creation (project name is ftbrony-master when downloaded from GitHub, not ftbrony).
FloatingStar/FTP-GMX,Favna/FTP3DS,mtheall/ftbrony
