[GSoC] Better chat log viewer

[Dan Lincan]

Hello,

I am interested in implementing new chat log viewer, so I have made a
draft on how I think it should look based on the ideas page. The draft
is at [1]. Please tell me where to add more details and what these
should be focused on( implementation details or features ).
