closes #54  plus more

Metadata generation:
For SPs md:ServiceName, md:ServiceNameDescription is generated based on mdui elements ;
if sitll  md:ServiceName has no values or no "en" found then tries to use values from md:Organization elements; If there is no values yet then entityID is used.

WebGUI : list entities, detai : until now OrgnanizationName was used ; 
   since now: found in order mdui:DisplayName (in gui lang, en), md:OrganizationDisplayName, md:OrganizationName

WebGUI: Introduced "info icon" - right side  (per user settings) - it will show/hide more description on the pages wich help endusers to navigate/understand the gui better - @todo add more informations 


Localized Description (general information) - became redundant - filed has bee removed


As column (ldescription) in provider table has been removed pleae don't forger to run doctrine-cli to update db
