Dual Monitor on PTL

Idea is to permit the inclusion of an additional monitor when working with PTL. Normally to have the matrix/list and XDS in one screen and the DICOM objects witihin another screen. Currently is possible to launch ZFP DICOM viewer as an API but we would like to improve by automatizing the display depending if the user works with one or two screens. With this, the idea is to keep the default configuration for those users with only one monitor (everything in one screen as it is right now) and make this display in 2 monitors for those users who have these deplyment
