Attachements in live chat#37

Hey,

attachements received in the livechat (from a users perspecitve) are currently not really usable.

Images can’t be opened in a light box to watch them fully.
The context-menu (when hovering over the image, right to the image) are without functionality.

Hi Benjamin. Viewing images from the livechat should be fixed.

The options next to messages are still to be decided, i.e. should a visitor delete messages?
