Dynamic element text item :

First : If the parent element of the text item is a slave,
the info use to create the text (both if option are 'element info' or 'composite text') are taken to the linked master element, and not the slave.
If the salve element is not linked, no information is taken.
Second : if the text is composed with the variable 'label' of the master (both if text from are 'element info' or 'composite text') double click on the text, act like a link and go to the master.
