[TASK] Do not add target attribute if lightbox is enabled

If config.fileTarget is set, per example to "_blank", the target is
set as fallbak on file link. The target is also added on click enlarge
link but it is not wanted if lightbox is enabled.

This patch ensure that the target attribute is not printed when
lightbox is enabled.
