Subject: [PATCH] Add leftover changes for 3.1

Adds various changes for a more complete 3.1 release

- cleaner "current slide" description in projector detail (grid with ellipsis)
- show the previously projected slides as ordered lists under the accordion
- fix a bug where everyone could access the projection manage view (although it was unfunctional without the correct permissions)
- assignment list now uses the correct ellipsis
- fixes a bug where the lable "list of speakers" was not translated on the projector slide
- Show a lock on the "list of speaker"-slide if it has been closed
- enable dialog tests that have previously been disabled
