Relevant to issue #17
The code is not working properly and there are still issues with transmiting the drawing and text to the shared activity instance.
As you can see in the commits, I used a custom gtk.TextView to replace the gtk Entry for the input field. One problem I faced was that, if I understand correctly, the sugar's gtk-widgets.css doesn't style textview in a similar way as entry. Would you suggest I manage the css for textview in the source code of chat's activity?
Also, currently when a user sends messages consecutively, they all bundle up in the same box. I was thinking that giving each separate message its own box, would look better. What do you think?
