Some changes will need to be adapted from PloneMeeting 1.4
- The "enableColorSystem" field has been renamed to "itemColorization" : set "itemColorization" to "modification_color" if "enableColorSystem" was "True", set it to "no_color" either. Then delete the old "enableColorSystem" attribute... --> ALREADY DONE IN MIGRATION TO 1.4???
- add the "Advices" action tab on every MeetingItem? portal_types --> OK
- in config.py/ploneMeetingUpdaters we removed 'Member' role to correct ticket #607. We now have to walk every meetingConfigFolders to set the 'ATContentTypes: Add File' permission correctly to the new ploneMeetingUpdaters list defined. --> OK
- add "itemsInCopy" and a "itemstoadvice" searches in portlet_meetingitems to open the new items in copy functionnality --> OK
- run UpdateSecuritySettings? from portal_workflow to update security for new roles and permissions --> OK
- check that new indexes are correctly added... --> OK
- update existing topics --> OK
