Rename group display names

[BornToBeRoot]

Add an edit button next to the delete button to rename groups?!

Currently i have to create a new group, add everyone to the group, delete the old one...

Group display names were implemented in #8255 - @nickvergessen it should be possible now to also implement the renaming, right?

[nickvergessen]

Well only displaying them. For 14 we should make it possible to store the displayname in the database.

something for 15 milestone?

[DerTomm]

... or 16 maybe? ;-)

What is needed for this to be implemented? It would really be great to be able to rename groups/roles. 👍

@redtux would you want to help out here?

@nickvergessen are the display names already stored in the database?

[redtux]

@violoncelloCH Depends on what needs to be done, as I am not a developer. Is this still related to #8255? (Is renaming possible in OwnCloud, so that I could have a look there?)
