Use mdui:DisplayName if it exists instead of OrganizationDisplayName

[martinhaase]

Currently, our (DARIAH, entityID="https://ldap-dariah.esc.rzg.mpg.de/idp/shibboleth") project's IdP is represented on the foodl.org list as "Gesellschaft für
wissenschaftliche Datenverarbeitung mbH". However, this only is the Computing Center's name that hosts our IdP, among many other IdPs. In the Foodl list, users only can tell from the logo that this is the DARIAH IdP. It would be much nicer if the software used the mdui:DisplayName, which is set for our IdP correctly, instead of the OrganizationDisplayName of the organization that happens to host our project.

It seems to me that the eduGain WAYF Browser component displays logos from entries in the metadata, but it does not take the DisplayName; it rather uses the OrganizationName.
Since the DisplayName is editable in the DFN-AAI Metadata Editor but not the OrganizationName both entries have the same display name. So a fix would be: Using DisplayName instead of OrganizationName for the list view.
