rebased on master and tested (not sure which things may not work because server is not ready yet..).

• When i ban some user, he is still shown in the participants list (same on web).

• He is also shown in the bans list. "Unban" seems to do nothing, after clicking he is still shown in the bans list. (for web, unban seems to work).

• Actual banning does not work, the user can still write..

• Date is always x.x.1970
