Issue box redesign

I complained before about the issue box looks. This is a proposed redesign.

The background of the issue is slightly lighter than the comments, so there is a clear distinction.

To make sure the issue then doesn't disappear, the shadow is slightly strongly (but still barely noticeable, to keep it flat).

The left top corner is round to highlight the status 'label', as it were a real label.

Small documentation update, add unixsocketperm

If you run gitlab as user ``git`` while redis runs as user ``redis`` and you add git to ``redis`` group, you'll need to set ``unixsocketperm = 0775`` to grant write access to group.
