Minor fix for DJ-ImageSlider (but you may need it)

Some of you struggled with the Notice visible in DJ Image Slider module: 

"Undefined property: stdClass::$rel" [...]

This updated version brings fix for it.

For the record: Please note that this was only a notice message and that kinds of messages are not intended for productive websites, but for software developers only (it doesn't harm the module logic at all). You should change error reporting on your productive websites to simple or none in the global joomla configuration.

• You can download latest version here.
• Or update DJ Image Slider using Joomla Updater.
