Option to open DIP in new page should also affect AIP and Representation levels

[luis100]

Currently, there is an option in configuration to open a DIP in a new page:

roda/roda-ui/roda-wui/src/main/resources/config/roda-wui.properties

Lines 1917 to 1920 in bba3b7a

	##########################################################################
	# Show DIP with URL with iframe settings
	##########################################################################
	ui.dip.externalURL.showEmbedded = true

But this only affects the disseminations slider. When opening a DIP in the disseminations card on the AIP or Representation level, we are sent to the embedded DIP page.

This is due to the common logic not following the same logic as the disseminations slider, ignoring the option to open a DIP in a new page.

But, opening a DIP in a new page is necessary when a DIP refers to an external URL that requires CAS authentication and iframe logins are disallowed.

Change common logic to behave the same way as the disseminations slider. The dissemination slider may then rely in the common logic.
